Homework Help: physics

Posted by Brian on Monday, October 19, 2009 at 3:18pm.

A popular pastime is to see who can push an object closest to the edge of a table without its going over. You push a 130 g object and release it 2.00 m from the table edge. Unfortunately, you push a little too hard. The object slides across, sails off the edge, falls 1.00 m to the floor, and lands 0.25 m from the edge of the table. If the coefficient of kinetic friction between the object and the table is 0.55, what was the object's speed (in m/s) as you released it, assuming that the local acceleration due to gravity is -9.80 m/s2?
