As shown in the picture below, a 47.2-kg block of ice slides down a frictionless incline 1.62 m long and an angle of elevation of 33.8. The coefficient of kinetic friction between the ice and the incline is 0.120. Mark pushes up on the ice parallel to the incline so that it slides down at constant speed. Find (a) the work done by the worker on the block of ice, and (b) the work done by gravity on the ice. 1.62m Upload Choose a File fk mg N Ө C
