Question

Recall that the formula for momentum is:

P=mv


Which of the following correctly shows momentum being calculated?

(1 point)

45 N=(9 kg) (5 m/s)


14 kg*/s=(9 kg) (5 m/s)s


45 kg*m/s=(9 kg) (5 m/s)


4 kg*m/s=(9 kg) (5 m/s)

Answer 1

Correct answer: 45 kg*m/s = (9 kg)(5 m/s)

Reason: p = m v = 9 kg × 5 m/s = 45 kg·m/s (units of momentum).
