From the top floor of a very high building, a kid drops a ball. Estimate the magnitude of the acceleration of the ball right after its collision with the ground in m/s^2.

Question

anonymous · Answer

the acceleration of gravity on earth is around 9.81 m/s^2

this number can be found in most if not all physics textbooks

the only case i can think of where the acceleration of gravity would be different is if there is drag, which the problem did not state so im assuming there is none

anonymous · Answer

air resistance is not negligible

perl · Answer

air resistance is ignored in this model, this is idealized

perl · Answer

also ignored is loss of energy due to heat, friction, sound
