A 1.6-kg block is attached to the end of a 2.0-m string to form a pendulum. The pendulum is released from rest when the string is horizontal. At the lowest point of its swing when it is moving horizontally, the block is hit by a 10-g bullet moving horizontally in the opposite direction. The bullet remains in the block and causes the block to come to rest at the low point of its swing. What was the magnitude of the bullet's velocity just before hitting the block?
 a. 1.0 km/s
  b. 1.6 km/s
  c. 1.2 km/s
  d. 1.4 km/s
  e. 1.8 km/s

Question 2

A 2.0-kg object moving 5.0 m/s collides with and sticks to an 8.0-kg object initially at rest. Determine the kinetic energy lost by the system as a result of this collision.
 a. 20 J
  b. 15 J
  c. 30 J
  d. 25 J
  e. 5.0 J
