A 45 kg block of ice slides down a frictionless incline 1.5 m long and
0.91 m high. A worker pushes up on the ice parallel to the incline so
that it slides down at constant speed.
- Find the force exerted by the worker.
- Find the work done on the block by the worker.
- Find the work done by the weight of the block.
- Find the work done by the normal force exerted by the surface of the incline on the block,
- and the net work done on the block.
