Question

A rubber ball with a mass of 0.140 kg is dropped from rest. From what height (in m) was the ball dropped, if the magnitude of the ball's momentum is 0.800 kg • m/s just before it lands on the ground?

My Notes Ask Your Teacher An object is traveling such that it has a momentum of magnitude 23.6 kgm/s and a kinetic energy of 327 1. Determine the following. (a) speed of the object in meters per second m/s

Answer 1

The momentum of the ball before falling on the ground is given, hence we can calculate the velocity of the ball before falling on the ground as,

p=mv v=

U= 0.8 0.140 = 5.714m/s

Therefore we can calculate the height required to reach this velocity before falling on the ground as, (We can use Conservation of Energy)

mv2 = mgh

, 72 h= 5.7142 h= 219.81 = 1.66m
