F = ma
work = force * distance
A crane lifts an 425-kg object vertically upward a distance of 95 m. How much work (in kJ) does the crane do on object if object accelerates upward at 1.8 m/s2? Neglect frictional forces. How much work (in kJ) does gravity do on the object if object accelerates upward at 1.8 m/s2? Neglect frictional forces.
