Part C Learning Goal: A box of mass 3.0 kg slides down a rough vertical wall. The gravitational force on the box is 29.4 N. When the box reaches a speed of 2.5 m/s, you start pushing on one edge of the box at a 45° angle (use degrees in your calculations throughout this problem) with a constant force of magnitude Fp = 23.0 N, as shown in ( Figure 1). There is now a frictional force between the box and the wall of magnitude 13.0 N. How fast is the box sliding 3.0 s after you started pushing on it? Find the box's speed of at 3.0 s after you first started pushing on it. ▸ View Available Hint(s) vf = 2.6 m/s Figure 1 of 1 45° 14 Submit Previous Answers Review Correct > Assuming that the angle at which you push on the edge of the box is again 45°, with what magnitude of force Fp should you push if the box were to slide down the wall at a constant velocity?
