This is a velocity question so u need to use uvaxt

51 seconds.

initial velocity of the kick = 28.06 m/s

The object's initial distance above the ground The object's initial velocity

The answer will depend on what "it" is, and on what its initial velocity is.

In a vacuum it would fall back to the same height at the same speed, 150m/s. It would then gain another minuscule fraction of speed as it fell from bat-height down to the ground. In the real world, a falling baseball will reach a maximum speed of around 42 meters per second because the air resistance slows it down. This is called Terminal Velocity.

No. What counts in this case is the vertical component of the velocity, and the initial vertical velocity is zero, one way or another.

To answer this question one would need to know the rock's initial height and velocity.

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)

Take acceleration of gravity = 9.8 m/s2 .The ball stops rising and starts falling in (100/9.8) seconds.It returns to the height of the bat in 2 x (100/9.8) = 20.408 seconds. (rounded)
