Momentum
Momentum = mass x velocity
Question: What is the momentum of a football player with a mass of 90 kg who is running at 5 m/s?

A baseball player feels a frictional force of 400 N as she slides into home. What is the impulse if the slide lasts 0.5 seconds?
Impulse = force x time
What would the impulse be if the same slide lasted 2 seconds?

Problem: A sport utility vehicle with a mass of 2000 kg is travelling at 100 km/h. The driver brakes to avoid a small animal in the road. The velocity changes from 28 m/s (100 km/h) to 8 m/s (30 km/h) in only 2 seconds. What force does the vehicle experience?
