p0oh asked:
An 865 kg airplane starts at rest on an airport runway at sea level.
(a) What is the change in mechanical energy of the airplane if it climbs to a cruising altitude of 2400 m and maintains a constant speed of 95.0 m/s?
(b) What cruising speed would the plane need at this altitude if its increase in kinetic energy is equal to its increase in potential energy?
