A popular pastime is to see who can push an object closest to the edge of a table without its going off. You push the 100 g object and release it 2.50m from the table edge. Unfortunately, you push a little too hard. The object slides across, sails off the edge, falls 1.50 m to the floor, and lands 20.0 cm from the edge of the table. If the coefficient of kinetic friction is 0.500, what was the object's speed as you released it?
