Ahelicopter, starting from rest, accelerates straight up from the roof of a hospital. the lifting force does work in raising the helicopter. (a) what type(s) of energy is (are) changing? ls each type increasing or decreasing ? why? (b) how is (are) the type(s) of energy that is (are) changing related to the work done by the lifting force? (c) if you want to determine the average power generated by the lifting force, what other variable besides the work must be known? an 810-kg helicopter rises from rest to a speed of 7.0 m/s in a time of 3.5 s. during this time it climbs to a height of 8.2 m. what is the average power generated by the lifting force?
