A ball is thrown horizontally from a window on the second floor of a building What is the vertical component of its initial velocity?
If a ball is thrown horizontally from a window on the second floor of a building, the vertical component of its initial velocity is zero.
What do need to know to determine how far projectile travels horizontally?
angle of projection,initial velocity and gravitational acceleration
What do you need to know to determine how far a projectile travels horizontally?
initial velocity, angle of launch, height above ground When a projectile is launched you can calculate how far it travels horizontally if you know the height above ground it was launched from, initial velocity and the angle it was launched at. 1) Determine how long it will be in the air based on how far it has to fall (this is why you need the height above ground). 2) Use your initial velocity to determine the horizontal component of velocity 3) distance travelled horizontally = time in air (part 1) x horizontal velocity (part 2)
A projectile is fired horizontally from a gun that is 71.0 m above flat ground emerging from the gun with a speed of 250 ms What is the magnitude of the vertical component of its velocity as it st?
If it's fired horizontally, then its initial vertical velocity is zero. After that, the vertical velocityincreases by 9.8 meters per second every second, directed downward, and the projectile hitsthe ground after roughly 3.8 seconds.Exactly the same vertical motion as if it were dropped from the gun muzzle, with no horizontal velocity.
What is the relationship between starting length and initial velocity of shortening?
The lighter the weight, the greater the initial velocity of shortening; inverse relationship.
Is acceleration greater when the object is thrown vertically or horizontally?
Acceleration is dependent on the initial velocity of how fast the object is leaving the projectile. The vertical acceleration is greater when the object is falling than when the object reaches the peak in height. However, if the object is thrown horizontally and there is no parabola in its shape then there is not as great of an acceleration.

Which will hit the ground first a ball thrown horizontally at 2 meters per second off a building 20 m high or a ball dropped by a hand at the same height?
They should reach the ground together, since their initial vertical speed is the same, namely zero.

What is the balloons initial velocity when a water balloon is dropped from the fifth floor of a building?
If you simply release an object, the initial velocity is always zero.
How will the final velocity be greater then the initial velocity?
It doesn't necessarily mean that the final velocity is always greater than the initial, if the initial velocity was at rest or 0 m/s then any form of movement would be greater. In cases where the final is smaller is like running into a wall or a decrease in acceleration.

Will gravitational energy have more or less energy if its dropped higher?
Gravitational energy basically refers to gravitational potential energy. The formula is: GPE = mgh (i.e., mass x gravity x height) In other words at a higher position, an object has more gravitational potential energy. Please note that once an object is dropped, it no longer has such gravitational potential energy. The potential energy is converted to kinetic (movement) energy; which of course will be greater if the initial potential energy was greater.
If final velocity is greater than initial velocity an object is?
Accelerating...or was accelerating.
