A valuable antique chest which weighs 1400 N is to be moved into a truck. To get the chest from the
ground onto the truck bed, which is 1.0 m higher, the movers push it up a rough ramp 4.0 m in length.
The coefficient of kinetic friction between the chest and the ramp is 0.20. Calculate the work done by the
movers on the chest if they push it at constant speed with a force, F, at an angle of B = 30° above the
