(1) A large moving ball collides with a small stationary ball. The momentum a. of the large ball decreases, and the momentum of the small ball increases. b. of the large ball decreases, and the momentum of the small ball decreases. c. of the small ball decreases, and the momentum of the large ball increases. d. does not change for either ball.

a. of the large ball decreases, and the momentum of the small ball increases.
b. of the large ball decreases, and the momentum of the small ball decreases.
c. of the small ball decreases, and the momentum of the large ball increases.
d. does not change for either ball.
(2) A sphere of mass 2 kg moving at a velocity 5 m/s strikes another sphere of mass 3 kg at rest. If they move together after collision what is their common velocity ?
(3) Two piloted satellites approach one another at a relative speed of 0.250 m/s, intending to dock. The first has a mass of 4.00×103kg, and the second a mass of 7.50×103kg. If the two satellites collide elastically rather than dock, what if their final relative velocity?
