Question

A sled weighs 200 N.It is held in place on a frictionless 20° 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) 188 N
B) 68 N
C) 213 N
D) 585 N
E) ​73 N

Quizplus · Accepted Answer

The normal force is the component of the sled's weight perpendicular to the slope. It is calculated as 200 N * cos(20°) ≈ 188 N.
