What is the momentum in kg.m/* of a 10 kg car travelling at
(a) 5 m/ (b) 20 cm/, and (c) 36 km/h ?
Mass of car, m = 10 kg
Momentum = m x v
(a) Velocity, v = 5 m/ Momentum = 10 x 5 = 50 kg.m/
(b) Velocity, v = 20 cm/ = 0.2 m/ Momentum = 10 x 0.2 = 2 kg.m/*
(c) Velocity, v = 36km/hr = 10 m/ Momentum = 10 x 10 = 100 kg.m/
