Ablock with mass of 10 kg is on a frictionless surface. one hand on the left side of the block is pushing it to the right. a second hand on the right side of the block is pushing it to the left. the block starts from rest. then hand 1 pushes with a force of 8 n and the block moves to the right a distance of 4 m, where it has a final velocity of 2 m/s. between its initial and final positions, how much work did hand 2 do?
