Chapter 2 & 3 Assignment 1. The diagram below shows a block of mass m resting on a 20° slope. The block has coefficients of friction H, = 0.80 and H = 0.50 with the surface. It is connected via a massless string over a massless pulley to a hanging block of mass 2.0 kg. a) What is the minimum mass m that will stick and not slip up the slope? 20° 2.0 kg b) If the minimum mass is nudged ever so slightly, it will start being pulled up the incline. Determine the magnitude of acceleration and tension along the rope.
