v2-v02=2gx,v0=0,g=9.806,x=120 m then v=48.5(m/s) in this calculation we have omit the air resistance

What is the rock's approximate velocity just prior to hitting the ground?

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


What happens when you release a ball from a height at rest?

It will fall with increasing velocity due to gravity and reach the peak velocity just before hitting the ground.


A tennis ball is dropped from 1.55 m above the ground It rebounds to a height of 0.824 mWith what velocity does it hit the ground?

31 m/s


A rock is dropped from a height of 80 m and is free fall what is the velocity of the rock as it reaches the ground 4.0 secounds later?

39 m\s downward


Is an object that is dropped will hit the ground before an object that is thrown horizontally from the same height?

No. They both hit the ground at the same time. This is because the VERTICAL component of velocity in both cases is the same.


Will the object that is dropped hit the ground before an object that is that it is thrown horizontally from the same height?

No. They both hit the ground at the same time, because the VERTICAL component of velocity in both cases is the same.


What is the speed of a diver hitting the water from a height of ten meters?

Terminal velocity


Why does a body exerts more force on ground when it is dropped from a certain height than when it at rest at the ground although in both the cases mass and acceleration is constant See discussion too?

Interesting question. But when the object is at rest the potential energy of the object is 0, on the surface that is. When it is on a height h it's potential energy increase and when it is dropped from that height all that potential energy gets converted to kinetic energy just before hitting the ground. This extra force comes from this kinetic energy.


Why does an object dropped from a certain height have more than twice the speed of an object dropped from half the height of the previous object?

Because they undergo an acceleration. Free fall velocity is the function of a square.


Does the height effect the bounce of the ball?

Yes, assuming the ball has elasticity and you haven't exceeded the height where the ball, when dropped, reaches terminal velocity.


Will a ball bounce higher if it is dropped from a greater height?

yes up to a certain point as there is more kinetic energy involved.The height of its bounce is limited by its terminal velocity


Does a higher muzzle velocity equal a longer range?

All other factors equal (bullet mass & frontal area, angle of barrel, etc) a higher muzzle velocity will make the bullet travel further horizontally as if falls to the ground. If the barrel is level when fired , the bullet will hit the ground at the same time as a bullet dropped simutaneously from muzzle height
