Question

Kim Hold a 2.0kg air rifle lossely and fires a bullet ofmass 1.0g. The muzzle velocity of the bullet is 150m/s. What is therecoil speed of the rifle? If the girl holds the rifle tightly against her body, therecoil speed is less. Calculating the new recoil speed assuming thegirl has a mass of 48kg.

Explanation / Answer

Applying the law of conservation of momentum as, m1u1+m2u2=m1v1+m2v2 (2+0.001)*0=2*v+0.001*150 v=-0.075m/s Hence we get by it.
