Question

A car of mass 600 kg is moving with a speed of 10 ms^-1 while a scooter of mass 80 kg us moving with a speed of 50 ms^-1. Compare their momentum.

Answer 1

Mass of the car, M = 600 kg

Mass of the scooter m = 80 kg

Velocity of car, v = 10 m/s

Velocity of scooter = 50 m/s.

We know that 

Momentum = mass x velocity

`"momentum of car"/"momentum of scooter" = "MV"/"mv" = ((600)(10))/((80)(50)) = 3/2`

Thus the required ratio is 3 : 2
