Asked by Sejul
I need formula/problem set ups for the following 2 problems:
1)Find The work done by the force in pulling an object on an inclined plane from A to B (ground level to top):
Length of incline (like a hypotenuse): 30 m
Height of incline (y axis): 10 m
Force = 20 N
object weight = 5 kg
2) Same diagram: Find the work done against gravity in moving the object from pt A to pt B

It depends in the direction of the force. Is is parallel to the incline?
If so, work done by the force is force*distance.
work done against gravity: mg*height
If so, work done by the force is force*distance.
work done against gravity: mg*height
