A ball of mass .05 kg moves with a velocity (17, 0, 0) m/s. It strikes a ball of mass .1 kg that is initially at rest. After the collision, the heavier ball moves with a velocity of (3, 3, 0) m/s.
a. What is the velocity of the lighter ball after impact?
b. What is the impulse delivered to the .05kg ball by the heavier ball?
c. If the time of contact between the balls is .03s, what is the force exerted by the heavier ball on the lighter ball?
