A sled weighs 100 N.It is held in place on a frictionless 20 $\degree$slope by a rope attached to a stake at the top;the rope is parallel to the slope.What is the normal force of the slope acting on the sled?
A)94 N
B)47 N
C)37 N
D)34 N

Question

Quizplus · Accepted Answer

The normal force is the component of the sled's weight perpendicular to the slope. It is calculated as 100 N * cos(20°) ≈ 94 N.
