The bird takes off from rest at the edge of a cliff, heading east, and accelerates at a rate of 1.21 m/s2. The osprey can decelerate at higher rate of 2.43 m/s2. The Osprey can reach top speeds of about 84 mph. When doing so, it does not flap its wings. Rather, it relies on its gravitational force to accelerate it downwards. a. Assuming that it starts from rest, and assuming that drag forces are slim, how long will it take for the osprey to reach its top speed? b. How far does it travel during this time? c. Near the top speed, drag forces become important, and in fact the terminal velocity is determined by the drag force.
