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

Question

As we know,

Momentum, p = mv

Where, m is the mass of the body

V is the velocity of the body,

(a) m = 2000 kg

v = 5 m/s

p = (2000) × (5)

= 10000 kg m/s

(b) m = 0.2 kg

v = 400 m/s

p = (0.2) × (400)

= 80 kg m/s
