A 0.40 kg pendulum bob starts with an initial velocity of 2.0m/s is released from a height of
0.275 m. It collides at the bottom of its swing with a 1.3 kg ballwhich is at initially at rest.
(a) Find the speed of the pendulum bob just before it strikes moremassive ball at rest.
(b) Assume the collision is elastic. Determine the magnitude anddirection of the velocities following
the collision.
(c) Using conservation of energy, determine the maximum height towhich ball travels following the
collision.
