Homework Help: physics

Posted by Kalen on Wednesday, October 7, 2009 at 12:45pm.

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 2.90 from the table edge. Unfortunately, you push a little too hard. The object slides across, sails off the edge, falls 1.50 to the floor, and lands 35.0 from the edge of the table. If the coeffecient of friction is .3 what is the objects speed as you released it?
I found the velocity in the x direction when the object falls off the table to be .63 m/s. how do i find the initial velocity?
