A bullet of mass 20 g is fired into ballistic pendulum of mass 3 kg initially at rest. The bullet exists from the other side of the ballistic pendulum with speed of 100 m/s while the ballistic pendulumswing throw an arc reaching a maximum height of 20.41 cm. a. calculate the speed of the ballistic pendulum just after the collision. b. calculate the speed of the ballet before it hits the ballisic pendulum. c. calculate the lost kinetic energy in this collision.
