O True O False QUESTION 2 2.5 points Save Answer Consider an object in uniform circular motion. Since p = mv , the object's linear momentum does not change. O True O False 2.5 points Save Answer QUESTION 3 Momentum is a o Scalar O Vector 2.5 points Save Answer QUESTION 4 Kinetic energy is conserved in elastic collisions. O True O False 2.5 points Save Answer QUESTION 5 A 1,667.61 kg car travels with a momentum magnitude of 31,553.55 N's, How fast is the car moving?

Explanation / Answer

1 ) True (Momentum conservation principle)

2) False (Momentum does change because of change in direction)

3) Vector ( Since it has both magnitude and direction)

4) False (Total Energy is conserved not only kinetic energy)

5) v = p/m = 18.92 m/sec

6) N.s
