A 5.0 kg crate is resting on a horizontal plank. The coefficient of static friction is 0.50 and the coefficient of kinetic friction is 0.40. One end of the plank is raised so the plank makes an angle of 30° with the horizontal. Find the minimum force that can be applied parallel to the plane to hold the crate at rest.

a. 4.49N

b. 0

c. 2.29N

d. 3.29N

e. 5.59N
