Question

5. A 1,600 kg car is moving south at 24 m/s. What is its momentum?
(Points : 1)
66 kgm/s south

66 kgm/s north

38,000 kgm/s north

38,000 kgm/s south


Question 6. 6. The velocity of a 150 kg cart changes from 6.0 m/s to 14.0 m/s. What is the magnitude of the impulse that acted on it?
(Points : 1)
900 kgm/s

1,200 kgm/s

3,000 kgm/s

2,100 kgm/s


Question 7. 7. An object's speed is 0.8 m/s, and its momentum is 200 kgm/s. What is the mass of the object?
(Points : 1)
250 kg

160 kg

128 kg

200 kg

Answer 1

1600 * 24 south

150 * 8

m = p/v = 200/.8
