A billiard ball is moving in the x-direction at 33.4 cm/s and strikes another billiard ball moving in the y-direction at 38.9 cm/s. As a result of the collision, the first ball moves at 50.6 cm/s, and the second ball stops. In what final direction does the first ball move?
 a. in the x-direction
  b. at an angle of 49.4 ccw from the x-direction
  c. at an angle of 40.6 ccw from the x-direction
  d. at an angle of 56.6 ccw from the x-direction
  e. Such a collision cannot happen.

Question 2

If a two-body collision is not head-on, then we may always assume that:
 a. momentum is conserved.
  b. kinetic energy is conserved.
  c. neither momentum nor kinetic energy are conserved.
  d. both momentum and kinetic energy are conserved.
