Problem 3.) Starting from rest a box (m 20.41kg) is pulled up an incline, by a force of 120N (the force is parallel to the slope of the incline). The incline is 10m long and is 3m tall. what is the total work done by the force pulling the box up the incline? w = 1200J What is the change in potential energy of the box? 600J What is the change in Kinetic Energy of the box? 600J
