A 40 kg cannon is loaded with a 10 kg cannonball and mounted on a 6 kg platform with wheels very low
To the ground. The wheeled platform is pushed and moves forward at 3 m/s horizontally. When the
Cannonball is fired out, the cannon recoils (backward) with a velocity of 2 m/s relative to the ground.
The cannonball then strikes a large solid block that weighs 32N and is sitting on the edge off a 50 m high
Cliff and becomes embedded in it. The combined mass is shot horizontally off the cliff. With what speed
Does the mass hit the ground at the bottom of the cliff?
