Question

Find the velocity of bullet of mass 5g which is fired from a pistol of mass 1.5g. The recoil velocity of pistol is 1.5ms⁻¹. ​

Answer 1

Answer:

450 m/s

Explanation:

mass of bullet (m2) = 5g = 0.005 kg

mass of pistol (m1) = 1.5 kg

velocity of pistol (v1) = 1.5 m/s

velocity of bullet = v2

By law of conservation of momentum,

v1 m1 = m2 v2

v2 = v1 m1 / m2

    = 1.5 x 1.5 / 0.005

    = 0.3 x 1.5/ 0.001

    = 450 m/s
