3. Sandra is having trouble with one of her assigned questions. She tosses her notebook to her friend Rahul for help. The book travels at 4 m/s and takes only 0.75 seconds to get to Rahul. How close are Sandra and Rahul sitting?

4. An alien (whose name cannot be spelled with our alphabet) is travelling from Alpha Centauri to our solar system, a distance of km ( x 1012 km). He makes this trip in just under three hours (2.8 h, to be exact). What is the speed of his spacecraft?

5. Light travelling from the Sun 1.44 x 108 km away reaches Earth in eight minutes. How fast is light travelling in km/s?

Stopping Distance Based on Velocity

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?
