Question

Item 6 Part C A block of weight u sits on a frictionless inclined plane, which makes an angle with respect to the horizontal, as shown. (Figure 1)A force of magnitude F, applied parallel to the incline, pulls the block up the plane at constant speed What is Wp, the work done on the block by the applied force F as the block moves a distance L up the incline? Express your answer in terms of F and other given quantities. View Available Hint(s) Wy= Figure 1 of 1 Submit Part D What is WOrmal, the work done on the block by the normal force as the block moves a distance L up the inclined plane? Express your answer in terms of given quantities View Available Hint(s)

Explanation / Answer

Solutions.

Part-C. ans.. F*L

part-D.ans...0

explanation....

workdone=force*distance.

as in the first case force and direction of motion

are in same direction.so.they just multiply with each other.

in 2nd case

.as normal force is perpendicular to motion.so

Force*distance =0.
