A crane lifts a 425-kg steel beam vertically upward a distance of 95 m. How much work (in kJ) does gravity do on the beam if the beam accelerates upward at 1.8 m/s2? Neglect frictional forces. Give your answer to 3 significant figures and remember that wo...

What is the work done by the movers on the chest when they lift it straight up 1.0 m compared to sliding it up the 4.0-m-long the frictionless ramp?
