Impulse and Momentum

Front

What is a system called when there is no external force on it?

Back

isolated

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? Options: 0 kgm/s, 30 kgm/s, 50 kgm/s, 10 kgm/s

Back

0 kgm/s

Front

The momentum of an object depends upon the object's ___________&_____________.

Back

mass and velocity

Front

What happens when a system winds up being isolated?

Back

The total momentum stays the same during collisions, etc.

Front

Impulse on a 3 kg ball when a 5 N force changes its velocity from +9 m/s to +3 m/s.

Back

-18 N s

Front

Cart A is pulled with a 2 Newton force for 2 seconds, and Cart B is pulled with a 1 Newton force for 3 seconds. Which cart experiences the greatest impulse?

Back

Cart A

Front

What does the impulse-momentum theorem state?

Back

The impulse on an object is equal to the change in momentum it causes.

Front

After collision, the two objects move off with different velocity. What type of collision is this?

Back

Elastic

A 40-kilogram mass is moving across a horizontal surface at 5.0 m/s. What is the magnitude of the net force required to bring the mass to a stop in 8.0 seconds?

Back

25 N

While playing pool, the white cue ball strikes the 8 ball. Before the collision, the cue ball's velocity was 10 m/s and the 8 ball was at rest. If both balls have a mass of 0.15 kg and the cue ball's velocity after the collision is 2 m/s, what is the 8 ball's velocity?

Back

8 m/s
