How much work would it take to push a # 1 kg # weight up a # 5 m # plane that is at an incline of # pi / 3 #?
The work done is found by
In any situation where a force acts and an object moves, the work done by or against that force is given by
Since the force we work against here is the force of gravity and the displacement is upward at an angle of
Therefore, the work done is
