A block sits on a frictionless sheet of ice. When it is pushed by a force of 15 N, the block will accelerate at a rate of 6.4 m/s^2. The block is then moved to the moon, where the acceleration of gravity is 1.62m/s^2. The coefficient of kinetic friction between the block and the moon's surface is 0.35. If the block is now pushed with the same force, what will be its acceleration?
