A golf ball moving forward with 1 unit of momentum strikes a heavy bowling ball that is initially at rest. After the golf ball bounces backward, the bowling ball is in motion with a momentum that must be
1) 1 unit. 2) more than 1 unit. 3) less than 1 unit. The magnitude of the golf ball's momentum after collision must be somewhat less than 1 unit, for otherwise a violation would occur in the conservation of 4) energy. 5) momentum. 6) both. 7) neither.
