Impulse and Momentum Quiz

An object has 15 Kg*m/s of momentum and a mass of 5 Kg. What is the object's velocity?

• 75 m/s

• 15 m/s

• 5 m/s

• 3 m/s

What type of collision is demonstrated in the picture below?

• Inelastic Collision

• Explosive Collision

• Explosion Collision

• Elastic Collision

What type of collision is demonstrated in the collision below?

• Explosive Collision

• Inelastic Collision

• Bouncy Collision

• Elastic Collision

Two identical cars, traveling at the same speed, crash into a wall. Since both cars have the same change in momentum, how can the force experienced by the passengers be decreased?

• Decreasing the time of the impact

• Increasing the time of the impact

• Both car accidents will experience the same force.

The impulse-momentum theorem states that

• the impulse on an object is equal to the change in momentum it causes 
• the force on a moving object is equal to the magnitude of the impulse.
• the impulse on an object is greater than the change in momentum it causes 
• the impulse on an object is less than the change in momentum it causes
