Transcribed Image Text:A 200-N sled of slides down a frictionless hillside that rises at 37° above the horizontal. What is the
magnitude of the normal force that the surface of the hill exerts on the sled?
1,
A) 200 N
B) 120 N
C) 160 N
D) 150 N
E) ON
Final formula:
Required steps:
1) Draw free body diagram
Add the forces acting on the
sled and label them
mg sin e
2) Choose reference frame
mg cos 0
mg
3) Find vectors components
FN = (
FG = (
No numerical values
4) Apply Newton's 2nd law
Fnet
= må
Fnet-x =
Fnet-y =
5) Solve for FN algebraically
You need to solve the above equation and find FN= ???? without
substituting numerical values, but using only variables
6) Check units
7) Substitute numerical values
