Physics - Center of Mass Question with Solution | TestHub
A large mass M is released from rest at the top of an inclined plane of angle and friction coefficient . At the same time, a pendulum consisting of a small mass m and (massless) string of length L is released at height L (horizontally). The large mass slides down the incline and smoothly onto the table, continues across the frictionless table, and collides with the pendulum's mass just as the pendulum has reached the bottom of its swing and is approaching the large mass. The two masses stick together after the collision.
For what initial height h of the mass M will the combined mass come to rest immediately after the collision? [Take ]
Options:
Answer:
Solution:
The pendulum bob reaches the bottom with speed, moving opposite to M. Combined mass stops when momenta cancel:.
Answer: (A)
