100-lb block is initially at rest and is placed along the inclined plane making an angle of 60° with respect to the vertical. If a horizontal force equal to 90 lb is applied to the block, and the coefficients of friction are μs = 0.20 and μk = 0.16 What is the direction of the block? What is the acceleration of the block? What is the total displacement of the block after 2 seconds?
