Question

A gun weighing 10 kg fires a bullet of 30 g with a velocity of 330 m/s. With what velocity does the gun recoil? What is the resultant momentum of the gun and the bullet before and after firing?

Answer 1

Apply formula

The resultant force is therefore 39N downward. For a 5-kg mass, the acceleration is therefore found as follows: 39N = F=ma = 5kg x a, so a = 7.8m/s^2
