9 km/s = 9000m/s
Gravity decreases the velocity of the object by 9.8 m/s each second.
The velocity at the top is 0 m/s
Equation 1: Velocity final = velocity initial - (9.8 m/s × time)
Final velocity =0 m/s
Initial velocity = 9000m/s
0 = 9000 - 9.8 t
9.8 t = 9000
t = 9000÷ 9.8
t = 918 seconds
Average velocity = (9000 + 0 ) ÷ 2 =4500 m/s
Height = average velocity × time
Height = 4500 m/s ×918 seconds=4,131,000 meters = 4,131 Km.
If you do not want to round, this equation will find the answer more accurately.
(velocity final) 2 - (velocity initial) 2 = 2 × acceleration × distance m/s2
0 - 90002 = 2 × 9.8 × d
d = 4,132,653.061 meters = 4,132.653061Km
I do not know of any measuring tool that measures that precisely!

How far below an initial straight line path will a projectile fall in one second?
Given no air resistance or other forces acting on the projectile, the projectile falls at a rate of ~9.81 meters per second. Given the position equation is at^2 + vt + x, where a is acceleration, v is velocity, x is the starting position, and t is time. Given an initial velocity and time of zero, the object will have moved ~9.81 meters in the first second.
True or false Because of earths gravitational pull and their own inertia projectiles travel in a straight path?
False Because gravity is constantly pulling on the projectile while the projectile is trying to move forward in a straight line, the projectile will move in a CURVED path and fall down to earth.
How do you find the launch velocity of a projectile that was fired straight up and came back down to the level it was launched at in 1.37 seconds?
the velocity at the start is the same as when it comes back down to the level. At the top velocity is zero and at the bottom the velocity is acceleration x time where time is 1.37/2 = 0.685s. Acceleration is that of gravity or 9.8 m/s/s, so projectile velocity is 9.8 x .685 = 6.7 m/s; in US system that is 22 ft/sec or 15 mph
How do you think the Coriolis effect would change if the Earth rotated twice as fast as it does?
the curving of the path would curve more than it is suppose to and the straight path due to the earths rotation would no longer be straight
How does the Coriolis effect cause?
The rotation causes the winds moving down from the poles to bend away from the equator..
What type of path does a projectile follow in the absence of air resistance?
Without air resistance, the path of a projectile over a small part of the Earth's surface, under the influence of gravity alone, is always a piece of a parabola ... as long as it's not launched straight up or straight down.
What is the angle for maxium altitude?
A baseball, cannonball, or other projectile launched at a 45° angle above the horizon will achieve maximum horizontal range. A projectile launched straight up will achieve maximum altitude, but you kind of have to watch it and be careful when it returns.
Is a feather falling in a vacuum projectile motion?
No, a feather falling in a vacuum is not considered projectile motion. Projectile motion involves an object being launched horizontally with a certain velocity while experiencing the force of gravity, causing it to follow a curved path. In a vacuum, there is no air resistance or drag force acting on the falling feather, so it falls straight down due to gravity.
How do you determine velocity time and height using quadratics?
The answers will depend on whether you are trying to determine these for a projectile or a ballistic object, whether it is travelling in a straight line (up-down) or a trajectory and what simplifying assumptions (for example, air resistance = 0) you make.The answers will depend on whether you are trying to determine these for a projectile or a ballistic object, whether it is travelling in a straight line (up-down) or a trajectory and what simplifying assumptions (for example, air resistance = 0) you make.The answers will depend on whether you are trying to determine these for a projectile or a ballistic object, whether it is travelling in a straight line (up-down) or a trajectory and what simplifying assumptions (for example, air resistance = 0) you make.The answers will depend on whether you are trying to determine these for a projectile or a ballistic object, whether it is travelling in a straight line (up-down) or a trajectory and what simplifying assumptions (for example, air resistance = 0) you make.
What causes the path of a projectile to be curved?
The path of a projectile can be curved due to the influence of external forces like air resistance, gravity, and other factors. These forces can affect the trajectory of the object, causing it to deviate from a straight line path.
How is it true that a projectile is a body in motion that cannot be treated as a particle?
A projectile is a body in motion under the influence of both gravity and air resistance, which makes its motion more complex than that of a particle with negligible size and air resistance. The trajectory of a projectile is affected by these forces, causing variations in its speed and direction during flight, whereas a particle typically moves in a straight line at a constant speed.
On what does the range of a projectile depend?
The speed and direction of the wind and the elevation of the machine firing the projectile. If the machine is pointing straight up, the projectile will not go very far. If it is pointing at the right elevation, the projectile will go farther.
How does the downward component of the motion of a projectile compare to the motion of free fall?
The downward component of the motion of a projectile is influenced by the initial velocity and angle of launch, resulting in a curved path known as a projectile motion. In contrast, free fall refers to the vertical motion of an object under the influence of gravity alone, where the acceleration is constant and the path is straight.
What is the vertical velocity at the top of the path of a projecticle thrown striaght up or launched at an angle?
The vertical velocity at the top of the path of a projectile thrown straight up is 0 m/s because it momentarily stops before falling back down. For a projectile launched at an angle, the vertical velocity at the top of the path depends on the initial velocity and launch angle, but it will also momentarily be 0 m/s before changing direction.
In the absence of air friction does the horizontal component of a projectile's velocity change as the projectile moves is this True False?
A projectile will travel on a straight line unless external forces act upon it. Gravity will pull the projectile downward, i.e. affect its vertical velocity component. This is why the projectile will decelerate upwards, reach a maximum elevation, and accelerate back down to earth. The force vector of air resistance points in the opposite direction of motion, slowing the projectile down. For example, If the projectile is going forward and up, air resistance is pushing it backwards (horizontal component) and down (vertical component). Without air resistance, there is no external force acting upon the horizontal velocity component and the projectiles ground speed will stay constant as it gains altitude and falls back down to earth.
What angle for firing projectiles gives longest time?
45 degrees to the horizontal will give the maximum flight time for a projectile. If a projectile was fired at 90 degrees to the horizontal, (straight upwards) the projectile will go straight upwards (ignoring the shape, form and aerodynamic properties of the projectile). Likewise if you were to fire a projectile at 0 degrees to the horizontal, the projectile would follow said course, IF gravity was not in effect; a projectile needs some form of vertical velocity to overcome gravity. Hence why 45 degrees will give you the longest distance and consequently flight time.
Is a cat leaping on a toy an example of projectile motion?
yes, because projectile motionis a curved path an object follows. SO if its leaping its ot going exactly straight.
