Computation. A construction crane lifts a 415-kg steel beam 180 m vertically into the air with an upward acceleration of 1.77 m/s². Ignoring any frictional forces, how much work We does the crane do on the beam? Wc = A × 105 J Record your numerical answer below, assuming three significant figures. Remember to include a "-" if/when necessary.
