A projectile is thrown with an initial velocity which has a horizontal component of 4 m s What will be its horizontal speed after 3s?
A projectile that is thrown with an initial velocity,that has a horizontal component of 4 m/s, its horizontal speed after 3s will still be 4m/s.
Ignoring air resistance what is the minimum initial speed a projectile must have at the Earths surface if the projectile is to escape the Earths gravitational pull?
8km/s
What is the horizontal range of a projectile initial velocity is doubled?
If "range" means that the shooter and the target are on the same level: quadrupled (if airesistance can be neglected). It takes twice the time until gravity "eats up" vertical velocity and during that time the projectile moves with double horisontal velocity. But if you shoot horisontally from a cliff at double velocity the flighttime will be the same and the range only doubled.
How does a projectile differ from an object free fall?
A projectile has an initial forward velocity.
How Does Projectile differ from a object in free fall?
The initial velocty of a projectile is non-zero.

Which information is needed to determine the horizontal distance a projectile travels?
-- the initial horizontal speed of the projectile -- the time it remains in flight before it hits the ground

What happens to the wavelength of a wave wen the frequency of the wave is doubled but the wave speed stays the same?
speed = freq. X wavelength Hence frequency and wavelength are inversely related when the speed is same. So if the frequency is doubled, then wavelength becomes half of the initial length.

The initial velocty of a projectile is non-zero.
What makes up a projectile motion?
Some of the factors that determine the movements of a projectile include: air resistance, force of gravity, initial launch velocity, the angle a projectile was launched at, and the objects initial elevation.
At what part of the trajectory does a projectile have minimum speed?
A projectile has minimum speed at the top of the trajectory.
Is initial velocity y the same for an angled launch and a horizontal launch if you use the same projectile launcher?
Yes. They will both initially be moving at the same speed.
What quantities remain constant in projectile motion?
All that I can think of are: 1.) Gravity 2.) Wind 2.A) wind speed 2.B) direction of wind 3.) Angle of trajectory 4.) Initial speed of projectile 5.) Material through which projectile travels (as in density) 6.) Mass of projectile 7.) Spin 7.A) speed of spin 7.B) axis/axes spining occurs on 8.) Shape of projectile 9.) Temperature of medium projectile is in 10.) Size of projectile (as in height, width, and depth) 11.) Weighting of projectile 12.) Obsturctions to projectile's path In a vaccuum, though, these are the variables: 1.) Speed of object 2.) Obstructions in path 3.) Gravity
