Question

A 500-kg cannon fires a 4.0-kg projectile with a velocity of 500 m/s relative to the ground. What is the recoil speed of the cannon?

Step 1

According to the law of conservation of momentum,

Step 2

Substituting the values, to find recoil speed of the cannon.

Step 3

The negative sign of the recoil speed indicates that the direction of th...
