If you need more space than is available, please attach additional sheets of paper. 1. A block of mass 5.0 kg is moving down a frictionless incline that makes an angle of 30 o with the horizontal. While the block is moving a distance of 2 m, a rope exerts a constant force of 15 N upward along the ramp. Throughout the problem use g=10 m/s 2 . (a) Draw all forces on the block. (b) Draw a vector to represent the net force on the block (label it clearly) and determine its magnitude. (c) Is the block speeding up or slowing down? Explain. (d) Find the work done by the net force ( net net W F s = • Δ a a ) Δ s=2 m m 30 o rope
