A block of mass m = 5.5 kg is pulled up a ? = 26° incline as in the figure with a force of magnitude F = 37 N.
(a) Find the acceleration of the block if the incline is frictionless in m/s^2.
(b) Find the acceleration of the block if the coefficient of kinetic friction between the block and incline is 0.11 in m/s^2.
