A steel ball is held by a ceiling-mounted electromagnet 4.0 m above the floor. A compressed-air cannon sits on the floor, 5.0 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 plastic ball. The two balls collide 1.4 m above the floor.What was the launch speed of the plastic ball?
