Momentum and Impulse

Front

The law of conservation of momentum states that:

Back

p before is the same as p after

Front

A 0.250 kg cart moving at 0.400 m/s has how much momentum?

Back

0.1 kg-m/s

Front

If 2 objects collide and stick together, what will happen to their velocities?

Back

velocities will decrease

Front

A 10kg toy truck moves at 5m/s East. It collides head-on with a 5kg toy car moving 10 m/s moving west. What is the total momentum of the system?

Back

0 kgm/s

Front

A large box slides across a frictionless surface with a velocity of 12 m/s and a mass of 4 kg, collides with a smaller box with a mass of 2 kg that is stationary. The boxes stick together. What is the velocity of the two combined masses after collision?

Back

8 m/s

Front

A biker with a mass of 75 kg moves along the path with a constant velocity of 5 m/s. What is the biker's momentum?

Back

375 kg m/s

Front

When the speed of an object is doubled, its momentum

Back

doubles

Front

In this type of collision, objects tend to "stick" together.

Back

velocity

Front

An 1 kg object moving to the right at 2 m/s collides inelastically with a 1 kg object moving to the left at 2 m/s. The final velocity of both objects will be: 0 m/s, 1 m/s, 2 m/s, 4 m/s

Back

0 m/s
