In the figure the upper ball is released from rest collides, Ask an Expert

Academics

In the figure, the upper ball is released from rest, collides with the stationary lower ball, and sticks to it. The strings are both 55.0 cm long. The upper ball has a mass of 1.60 kg and it is initially 10.0 cm higher than the lower ball, which has a mass of 3.50 kg.

A. Find the magnitude of the momentum of the 1.60-kg ball just before it collides with the 3.50-kg ball.

B. Find the speed of the two balls (now stuck together) at the instant immediately after the collision.

C. Find the frequency of the pendulum motion after the collision.

D. Find the maximum angular displacement of the motion after the collision
