Back

20000 kg * m/s north

Front

Front

While playing pool, Emma notices that the pool balls bounce apart. What type of collision is this?

Back

Elastic

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

inelastic

Front

A 3,000 kg truck moving at +10 m/s hits a 1,000 kg parked car which moves off at +15 m/s after the collision. What is the velocity of the truck after the collision?

Back

5 m/s

Front

When two objects interact in an isolated system,

Back

the total momentum is always conserved

Front

The law of conservation of momentum states that:

Back

p before is the same as p after

Front

When two ice skaters initially at rest push off one another, their final momenta are

Back

equal in magnitude and opposite in direction
