Scott Macartney, a US Olympic Ski Team member was going 39 m/s in the downhill ski race when lost his balance and fell. He has a mass of 65Kg.

1

What was his momentum?

PYS.C.6.c

1

How fast would a ping-pong ball (mass 0.003Kg) have to be traveling to have the same momentum as Scott Macartney just before he fell?

PYS.C.6.c

1

What is the relationship of momentum and impulse?

Inverse

There is no relationship

Impulse is the change in momentum

As momentum increases, impulse decreases
