- A rescue helicopter is hovering over a person whose sailboat has capsized. One of the rescuers tosses a life preserver straight down to the person with an initial speed of 1.25 m/s and observes that it takes 1.75 s to reach the water. How high above the water was the preserver released? Note that the downdraft of the helicopter reduces the effect of air resistance on the falling life preserver, so that an acceleration equal to that due to gravity is reasonable.arrow_forwardAn object is released from rest on a planet that has no atmosphere.

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.
