1. A 20 g piece of clay moving at a speed of 50 m/s strikes a 500 g pendulum bob at rest. The length of a string is 0.8 m. After the collision the clay-bob system starts to oscillate as a simple pendulum.
a. What is the speed of the clay-bob system after the collision?
b. What is the maximum angular displacement of the pendulum?
c. What is the period of the clay-bob oscillating system?
d. What is the total energy of the oscillating system?
The pendulum bob makes one complete oscillation and the string breaks at the lowest point.
e. What is the maximum horizontal distance of the bob when it strikes the floor 0.7 m below?
