A 319.4-lb chest is to be moved into a truck. The truck bed is 4.9 ft higher than the ground. What is the work done by the movers on the chest if they use their 12.0-ft-long ramp. They push the chest on a wheeled dolly, which in a simplified model is equivalent to sliding it up a frctionless ramp.

If you do this on the floor, it would be best to have a hard surface, so the slinky is not sliding against carpet. Practice until you are able to produce standing waves with two nodes(at the two ends), three nodes (two at the ends and one in the middle), and...

HDT Truck Company HDT Truck Company has been located in Crown Point, Indiana, since 1910. Its only products— large trucks—are built to individual customer specifications. The firm once produced automobiles but dropped out of the auto business in 1924. The firm nearly went out of business in the late 1930s, but by 1940 its fortunes were buoyed by receipt of several military contracts for tank retrievers—large-wheeled vehicles that can pull a disabled tank onto a low trailer and haul it...
