CSEC Physics · January 2010 · Paper 2 · Question 2(b)(ii)

A police recruit shot at a stationary target of mass 5.0 kg with a bullet of mass 0.1 kg. The target was mounted on low-friction wheels. After the bullet struck and embedded in the target, the target with the embedded bullet sped off with a velocity of 6.0 m s⁻¹.

Calculate the velocity of the bullet just before it hit the stationary target.
