Question

Calculate the momentum of the following:
(a) an elephant of mass 2000 kg moving at 5 m/s
(b) a bullet of mass 0.02 kg moving at 400 m/s​

Answer 1

Answer:

A) 10000 kgm/s

B) 8 kgm/s

Explanation:

A) Given,

Mass = 2000 kg

Velocity = 5 m/s

Momentum = mass × velocity

M = 2000 × 5

M = 10000 kg m/s

B) Mass of bullet =0.02 kg

Velocity =400 m/s

Momentum =0.02×400=8 kg.m/s
