A box with mass 7.4 kg (starting at point A) slides down a ramp inclined at 15 degrees. It was released from rest 2.25 meters above the ground. Near the bottom of the ramp, the box hits a spring of length 1.34 meters with a k of 1.8 N/m which is compressed 0.36 meters (point B). What is the height of the box at B? How much work does friction do from point A to point B? What is the distance from point A to point B along the ramp? What is the coefficient of friction between the ramp and the box? At this point, the spring releases and the box moves back up the ramp (to point C). How high above
How high above the ground is the box when it stops? The height of the box at point B is ? . The work done by friction between A and B is . The distance from point A to point B along the ramp is . The coefficient of friction is 0.27 . The box is ? above the ground at point C.
