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 3.00 m from the table edge. Unfortunately, you push a little too hard. The object slides across, sails off the edge, falls 1.30 m to the floor, and lands 25.0 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? I've tried a lot of different things, suggestions?
