Problem: A 35 g steel ball is held by a ceiling-mounted electromagnet 3.6 m above the floor. A compressed-air cannon sits on the floor, 4.6 m to one side of the point directly under the ball. When a button is pressed, the ball drops and, simultaneously, the cannon fires a 25 g plastic ball. The two balls collide 1.4 m above the floor.What was the launch speed of the plastic ball?

A 35 g steel ball is held by a ceiling-mounted electromagnet 3.6 m above the floor. A compressed-air cannon sits on the floor, 4.6 m to one side of the point directly under the ball. When a button is pressed, the ball drops and, simultaneously, the cannon fires a 25 g plastic ball. The two balls collide 1.4 m above the floor.
