Acrane lifts a 425 kg steel beam vertically a distance of 66 m. how much work does the crane do on the beam if the beam accelerates upward at 1.8 m/s2? neglect frictional forces

The solution to the problem is as follows:

W=Fd=mad=425*1.8*66 =50490 J

Therefore, it takes 50490 J of work the crane will do to accelerate the beam upward at 1.8 m/s^2.
