Question

If a 100-pound block of ice is placed on an inclined plane that makes an angle of 35° with the horizontal, how much friction force will be required to keep it from sliding down the plane? Choose the equation that could be used to solve the problem if x represents the force required to keep the block from sliding down the plane.

Answer 1

F = 100(.5736)

= 57.36 lbs. (rounded off to 2 decimal places)

2) sin60 = .866

F = 18(.866)

= 15.59 lbs. (rounded off to 2 decimal places)

Explanation:

F = friction

Answer 2

100sin35° = x
