Question

what is change in momentum of a car weighting 1500 kg when its speed increases from 36 kg/hr to 72 km/hr uniformly ?​

Answer 1

Answer:

15000kgm/s

Explanation:

V final= 72 km/hr = 72×5/18= 20 m/s

V initial= 36 km/hr = 10 m/s

∆p= m(V final - V initial)

∆p= 1500(20-10)

∆p= 1500×10

∆p= 15000 kgm/s
