A box of mass 3.06kg slides down a rough vertical wall. The gravitational force on the box is 30N. When the box reaches a speed of 2.5m/s, you start pushing on one edge of the box at a 45? Angle (utilize degrees in your calculations throughout this problem) with a constant force of magnitude Fp = 23N, as shown in. There is now a frictional force among the box and the wall of magnitude 13N. How fast is the box sliding 3.0s after you started pushing on it?
