Ablock of mass m = 2.0 kg lies on a rough ramp that is inclined at an angle θ = 20oto the horizontal. a force f of magnitude 5.0 n is applied to the block in the horizontal direction (not parallel to the ramp).a) if this force is just large enough to start the block moving down the ramp, what is the coefficient of static friction μsbetween the block and the ramp? b) if the coefficient of kinetic friction between the block and the ramp has a value of 0.40, what is the magnitude of the acceleration of the block along the ramp as this force is applied to the block? c) what is the work done by this applied force if the block travels a distance of 2.0 m down (i. e., parallel to) the ramp?
