2. Suppose instead that the hand were to push with a force of the same magnitude as before but do zero work. The displacement of the block is the same as before. In the space at right, draw an arrow to show the direction of the force by the hand. Displacement Force on block of block by hand 3. A block is initially moving to the right on a level, frictionless surface. A hand exerts a constant horizontal force on the block that causes the block to slow down (stage 1), turn around, then move in the opposite direction while speeding up (stage 2). 1. Complete the table below. Draw arrows to indicate relevant directions, and take the positive x-direction to the right.
