Three Forces,F1 = 20

Question 60

Short Answer

Three forces,F1 = 20.0 N,F2 = 40.0 N,and F3 = 10.0 N act on an object with a mass of 2.00 kg which can move along a frictionless inclined plane as shown in the figure.The questions refer to the instant when the object has moved through a distance of 0.600 m along the surface of the inclined plane in the upward direction.Calculate the amount of work done by
(a)F1
(b)F2
(c)F3.
