You fire a bullet into a 2 kg wooden block that is hanging at the bottom of a pendulum. When
the bullet strikes the block, the pendulum swings upward. The bullet has a mass of 0.02 kg
and strikes the block with a speed of 300 m/s.
a. What is the speed of the block and bullet when they first start moving together?
b. What is the maximum height reached by the pendulum?
