You push a 10 kg box across the floor. The box is initially at rest. You apply a force on the box for
0.05 seconds. If the velocity of the box is 50 m/s after you push it, what is the net force you applied
to the box? (Hint: remember impulse! F*t = m*v2 - m*v1)

In a game of pool, ball a is moving with a velocity v0 of magnitude v0 = 15 ft/s when it strikes balls b and c, which are at rest and aligned as shown. knowing that after the collision the three balls move in the directions indicated and assuming frictionless surfaces and perfectly elastic impact (that is, conservation of energy), determine the magnitudes of the velocities va, vb, and vc.
