An ice skater applies a horizontal force to a 20 kg block on frictionless, level ice, causing the block to accelerate uniformly at 1.4 m/s² to the right. After the skater stops pushing the block, it slides onto a region of ice that is covered with a thin layer of sand. the coefficient of kinetic friction between the block and the sand covered ice 0.28.
What is the magnitude of the force applies to the block by the skater?
