Question

You are trying to knock over a bowling pin by throwing a ball at it. You can either choose a rubber bouncy ball or a sticky clay ball of equal mass. the clay ball sticks to the pin but rubber ball bounces at the same speed. Assume that you can throw both balls with the same initial speed. It means that both balls with the same initial speed. it means both balls have equal initial momentum, p(ix). what is the final momentum of each ball, what is the change in momentum of each ball, which ball will experience large impulse during the collision, explain in terms of change in momentum and which ball has the larger chance of knocking over the bowling pin, explain.

Explanation / Answer

Final momentum for clay ball is pf = m*vf = m*0 = 0 kg m/sec

final momentum of rubber ball is pf = m*vf = -m*vi = -pi(x)

vi is the initial speed of rubber ball

change in momentum

for clay ball is pi(x)

for rubber ball pi(x) + pi(x) = 2*pi(x)

impulse = change in momentum

So the ball with large charge in momentum will experience large impulse

So the rubber ball will experience the large impulse

and rubber ball has the larger chance of knocking over the bowling pin
