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 3.00m from the table edge. Unfortunately, you push a little too hard. The object slides across, sails off the edge, falls 1.50m to the floor, and lands 25.0cm from the edge of the table.
If the coefficient of kinetic friction is 0.400, what was the object's speed as you released it?
