Question

find the change of momentum Weighting 1500kgwhen its speed increases from 36kmperhour to 72 km perhour?

Answer 1

here is your answer

given :

mass = 1500 kg

initial velocity (u) = 36 km/hr = 36*(5/18) = 10 m/s

final velocity (v) = 72 km/hr = 72*(5/18) = 20 m/s

solution :

change in momentum = final momentum - initial momentum

change in momentum = mv-mu

change in momentum = m(v-u)

change in momentum = 1500(20-10)

change in momentum = 15000 kgm/s
