What is the momentum in kg.m/s of a 10 kg car travelling at a) 5 m/s b) 20 cm/s c) 36 km/h

Answer»

Mass of car, m = 10 kg 

Momentum = mv 

a) Velocity, v = 5 m/s 

Momentum = mv = 50 kg.m/s 

b) Velocity, v = 20 cm/s = 0.2 m/s 

Momentum = mv = 2 kg.m/s 

c) Velocity, v = 36 km/h = 10 m/s 

Momentum = mv = 100 kg.m/s
