Alex, Ben, and Chris are trying to move a heavy rock of mass 230 kg. Alex pulls the rock North with a force of 360 N, Ben pushes the rock East with a force of 510 N and Chris pulls the rock with a force of 520 N at an angle 20.0 degrees East of North. They end up moving the rock 2.8 meters 50.97 degrees North of East. In the following answer boxes, enter the work done by Alex, Ben and Chris respectively.

    A homeowner is trying to move a stubborn rock from his yard which has a mass of 525 kg. By using a lever arm (a piece of metal rod) and a fulcrum (or pivot point) the homeowner will have a better chance of moving the rock. The homeowner places the fulcrum d = 0.233 m from the rock so that one end of the rod fits under the rock\'s center of weight. If the homeowner can apply a maximum force...

    3. Workhorses You are working in a 19th century warehouse trying to move a 200 kg box across the floor. Previous workers have estimated that the force of friction exerted by the floor on a box of this size and type is 1000 N. You harness two horses to the box. Albert Horse pulls in a direction 10° west of north and Gwnedolyn Horse pulls in a direction 20° east of north. The box slides due north at a constant...
