Question

A gun is designed that can launch a projectile of mass 10 kg at a speed of

200 m/s. The gun is placed close to a straight, horizontal railway line and aligned

such that the projectile will land further down the line. A small rail car of mass

200 kg and traveling at a speed of 100 m/s passes the gun just as it is red.

Assuming the gun and the car are at the same level, at what angle upwards must

the projectile be red in order that it lands in the rail car?
