Question

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

Answer 1

Answer:

Mass of car , m=10 kg

Momentum =m×v

a) velocity ,v=5 m/s Momentum=10×5=50 kg.m/s

b) velocity , v=20 cm/s=0.2 m/s Momentum=10×0.2=2 kg.m/s

c) velocity , v=36 km.hr=10 m/s Momentum=10×10=100kg.m/s

Answer 2

Explanation:

(c) 36km/h?
