Question

2. A bullet of mass 20 g is horizontally fired with a velocity 150 m/s from a pistol of mass 2 kg. What is
the recoil velocity of the pistol?
3. A van of mass 2000 kg travelling at 40 m/s dashes into the rear of a bus of mass 10,000 kg moving in
the same direction at 5 m/s. The van bounces backward after collision with a speed of 10 m/s. What
was the velocity of the bus after the impact ?​

Answer 1

Explanation:

Answer. Let v be the recoil velocity of the pistol. Thus, the recoil velocity of the pistol is 1.5 m/s.
