A 55 kg block of ice slides down a frictionless ramp that is 2.0 m long and 0.91 m high. A worker pushes up against the ice, parallel to the ramp, so that the block slides down the ramp at constant speed.

a. Find the force exerted by the worker.

b. Determine the work done on the block by the workerâ??s force.

c. Determine the work done on the block by the gravitational force.

d. Determine the work done on the block by the normal force.

e. Determine the total work done on the block.
