Question

question 6 (1 point)
a 200 - n sled slides down a frictionless hillside that rises at 37° above the horizontal. what is the magnitude of the force that the hill exerts on the sled parallel to the surface of the hill?
a) 200 n
b) 150 n
c) 0 n
d) 120 n
e) 160 n

Explanation:

Step1: Analyze forces on sled

The normal force exerted by the hill on the sled is perpendicular to the surface of the hill. There is no component of the normal - force parallel to the surface of the hill on a friction - less surface. The only forces acting on the sled are its weight and the normal force. The normal force has no parallel component to the surface of the hill.

Step2: Determine parallel force

Since there is no friction and the normal force has no component parallel to the surface of the hill, the magnitude of the force that the hill exerts on the sled parallel to the surface of the hill is 0 N.

Answer:

C. 0 N
