A 3-kg block has a speed of v=9 m/s at point O as it travels along a rough incline OA with μk=0.25. It then hits a spring with k=500 N/m at point A and eventually comes to a temporary stop as it reaches its highest point. Let x be the deformation of the spring when the block reaches a temporary stop.Which of the following gives the correct expression for the work done by friction on the object as it goes from O to the highest point reached by the block? a. -6.91(2/sin20+x) b. 6.91(2/sin20+x) c. -6.91(2+x) d.6.91(2+x)
