A 500-kg helicopter ascends from the ground with an acceleration of 2.00m/s^2. Over a 5.00 seconds interval, what is (a) the work done by lifting force, (b) the work done by the gravitational force, and (c) the new work done on the helicopter?© BrainMass Inc. brainmass.com March 4, 2021, 5:51 pm ad1c9bdddf
First we need to calculate the height the helicopter ascends, say H(m). Then we use the Newton's ...
This solution determines the work done by the lifting force, gravitational force, and the new work done on the helicopter.
