What type of energy does an object with momentum have?

3

If an object traveling at 20 m/s (about 44 miles per hour) has a momentum of 800Kg*m/s, what is the object’s mass?

2

What happens to the momentum if the mass is quadrupled?

2

What happens to the momentum if the velocity is tripled?

3

What is the momentum of an object that is at rest?

3

A 100Kg man is running at 5.6m/s. What is his momentum?

3

If a 40 Kg object has a momentum of 400Kg*m/s, how fast is it traveling?

3

What is the impulse of a hammer that exerts 25 N of force for 0.02 s on a nail?

3

A locomotive has a mass of 200,000 Kg. It is moving at 10 mph (4.5 m/s). How fast would a car (mass 1000Kg) be traveling to have the same momentum?

3

What is the impulse of a 2400 kg car if it was moving at 18 m/s and comes to a stop?

2

What is the force exerted on a 120 kg bike as it comes to a stop from 7.2 m/s in 1.8 s?

2

What is the momentum of a ball that hits a net with a force of 17.4 N for 1.4 s?

Scott Macartney, a US Olympic Ski Team member was going 88 miles per hour (39 m/s) in the downhill ski race when lost his balance and fell. He has a mass of 65Kg.

2

What was his momentum?

2

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?

1

Order the following from greatest momentum to least

0.3 kg mass moving at 200 m/s
300 kg mass moving at 5 m/s
3,000 kg mass moving at 0.01 m/s
3 kg mass moving at 15 m/s

1

What is the relationship of momentum and impulse?

1

Calculate the impulse of a 710kg racecar that strikes a solid wall with a 2,115,800 N force in 0.03 seconds.

Any object that has momentum must also have __________
