A box slides down a plank of length d that makes an angle of θ with the horizontal as shown. μk is the kinetic coefficient of friction and μs is the static coefficient of friction. 1.Enter an expression for the minimum angle θ (in degrees) the box will begin to slide. 2.Enter an expression for the nonconservative work done by kinetic friction as the block slides down the plank. Assume the box starts from rest and θ is large enough that it will move down the plank. 3.For a plank of any length, at what angle θ (in degrees) will the final speed of the box at the bottom of the plank be 0.85 times the final speed of the box when there is no friction present? Assume μk = 0.39.
