Calculate the momentum of a toy car  of mass 300 g moving with a speed of 18 kmh-1.
Asked by Topperlearning User | 20 Sep, 2016, 11:20: AM
answered-by-expert Expert Answer

Momentum = Mass × Velocity

Given: Mass = 300 g = 0.3 kg

begin mathsize 12px style Velocity equals 18 space kmh to the power of negative 1 end exponent equals fraction numerator 1800 space straight m over denominator 3600 space straight s end fraction Momentum equals 0.3 space kg space cross times space fraction numerator 1800 space straight m over denominator 3600 space straight s end fraction Momentum equals 0.3 space kg space cross times space 5 space straight m divided by straight s space Momentum equals 1.5 space kg space cross times space straight m divided by straight s end style
