Question

A hockey puck with a mass of 0.12 kg is traveling across the ice at a velocity of 150 m/s downfield. What is the momentum of the hockey puck?(1 point)
Responses

M=18 kg*m/s
Mass equals to 18 kilogram asteric metre per second

P=18 N
Power equals to 18 Newton

P=18 kg*m/s
Power euqals to 18 kilogram asteric metre per second

P=8*10−4 kg*m/s

Answer 1

Momentum p = m v = 0.12 kg × 150 m/s = 18 kg·m/s. (Direction: downfield, so p = +18 kg·m/s if that direction is taken as positive.)
