Question

A loaded truck with a mass of 38000kg is travelling at a speed of 1.20m/s. What will be the velocity of a 1200kg car if it has the same momentum.

Answer 1

V = 38000*1.2/1200=38 m/s

Answer 2

Mass of truck = 38000kg

Mass of car =1200kg

Momentum = mass * velocity

Velocity of truck = 1.20m/s

Velocity of car =?

P truck = Pcar

38000*1.2= 1200*V

V= 38000*1.2/1200

V= 38m/s
