# Question

A wheeled car with a spring-loaded cannon fires a metal ball vertically (Fig. 3.24). If the vertical initial speed of the ball is as the cannon moves horizontally at a speed of 0.75 m/s,

(a) How far from the launch point does the ball fall back into the cannon, and

(b) What would happen if the cannon were accelerating?
