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

both!
Assuming that each object is held with its center of gravity at the same height, and that each is dropped cleanly, with no rotation induced, the one whose lowest part is closest to the ground when dropped will hit first.
They would hit the surface together, after a very long time. Gravity on Ceres is pretty light.
Assuming no air friction, neither and no it would not be different. In real life, I imagine the brown trout would hit first.
To answer this question one would need to know the rock's initial height and velocity.
It will fall with increasing velocity due to gravity and reach the peak velocity just before hitting the ground.
31 m/s
39 m\s downward
No. They both hit the ground at the same time. This is because the VERTICAL component of velocity in both cases is the same.
No. They both hit the ground at the same time, because the VERTICAL component of velocity in both cases is the same.
Terminal velocity
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.
Because they undergo an acceleration. Free fall velocity is the function of a square.
Yes, assuming the ball has elasticity and you haven't exceeded the height where the ball, when dropped, reaches terminal velocity.
yes up to a certain point as there is more kinetic energy involved.The height of its bounce is limited by its terminal velocity
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
