The figure below shows an initially stationary block of mass m on a floor. A force of magnitude F = 0.570mg is then applied at upward angle = 22.

(a) What is the magnitude of the acceleration of the block across the floor if (a) s = 0.600 and k = 0.500?

(b) What is the magnitude of the acceleration of the block across the floor if s = 0.400 and k = 0.300?
