Problem 3: A 5-kg box slides down a ramp. The ramp is 1 m in length and inclined at an angle of 30° as shown. The box starts from rest at the top. The surface friction coefficient is 0.28. 1. Use energy methods to determine the speed of the box at the bottom of the ramp. 2. How far does the box slide before stopping on the horizontal floor if it continues to experience the same friction coefficient. 8-0 0.500 -1.00 m 20.0
