Final answer:Only gravity does non-zero work on the wooden block as it slides down the frictionless ramp, since gravity has a component along the ramp and the ramp is frictionless, meaning no work is done by frictional force or spring force, and the normal force acts perpendicular to the movement.Explanation:Steven carefully places a 1.65-kg wooden block on a frictionless ramp, so that the block begins to slide down the ramp from rest. The ramp makes an angle of 58.3° up from the horizontal. We need to determine which forces do non-zero work on the block as it slides down the ramp. Work is done by a force when the force results in displacement and there is a component of the force in the direction of displacement. On a frictionless ramp, this means that:The normal force does zero work because it acts perpendicular to the displacement of the block.Gravity does non-zero work because it has a component along the ramp, which is parallel to the direction of movement.As there is no information about a spring being attached to the block, we assume spring force does not apply in this scenario and so does no work.Frictional force also does zero work since it is stated that the ramp is frictionless.Hence, the correct answer is that gravity does non-zero work on the wooden block as it slides down the ramp....
