Question:
Once the box begins to slide and accelerate, kinetic friction acts to slow the box with a coefficient of kinetic friction μk = 0.1. The raised end of the surface can be lowered to a point where the box continues sliding but does not accelerate. The critical angle at which this happens,θc', can be found from the equation tan θc' = μk.
(a) What is this critical angle for the box?
(b) If the box is 5 ft from the pivot point, at what height will the box stop accelerating?
