| Sally spares no effort in pinning down this line of bowling. So far, her dog is one up on her!
Sally is a power bowler; her 5-kg ball has a velocity of 8 m/s when it strikes the 2-kg pin head on. After the collision, the ball's velocity is 4 m/s. Since you know that total momentum is conserved, you should be able to easily calculate the velocity of the pin after the collision! |
