Question

a bullet of mass 20g is horizontilly fired with a velocity 150m/s from a pistol of mass 2kg.what is the momentum of the of the bullet

Answer 1

Mass of the bullet (m) = 20 grams = 0.02 kg

Velocity of the bullet (v) = 150 m/s

Momentum of the bullet (p) = mass × velocity

Momentum of the bullet (p) = 0.02 × 150 kg m/s

Momentum of the bullet (p) = 3 kg m/s

Hence, the momentum of the bullet is : p = 3 kg m/s
