Question: 10 kg 55 N 8=37 5m A string exerts a tension force of 55 N on a 10-kg block as it moves a distance

10 kg 55 N 8=37 5m A string exerts a tension force of 55 N on a 10-kg block as it moves a distance of 5 m up a frictionless incline, as shown. The string pulls parallel to the incline. a) Find the total external work done on the block-earth system as the block moves 5 m up the incline. b) Find the change in gravitational potential energy for the block-earth system as the block moves 5 m up the incline. c) Find the change in kinetic energy for the block-earth system as the block moves 5 m up the incline.
