A 1.1 kg seagull takes off from a piling along the California coast and accelerates in 0.50 s to a flight speed of 7.5 m/s. Assuming the seagull flies along a horizontal path (at the same height as its takeoff), what average power is delivered by the bird’s wings during the takeoff?
Homework Answers
Find the change in kinetic energy and use work energy theorem
where work is equal to change in kinetic energy. Divide the work by
time to find the average power as shown below

The OntarioTech rowing team is moving along at a steady speed of 17.86 m/s. The cox issues an order to increase the rate of speed of the boat and the boat uniformly accelerates to reach a final speed of 41.1 m/s. If the boat traveled a distance of 53 m before reaching the final velocity, what was the boat’s acceleration over that distance? An airplane accelerates down a runway at 13.7 m/s2 for 12.1 s until it finally lifts off...

1. A Cessna 206H has a mass of 1000 Kg, a takeoff speed of 34 m/s (about 67 kn) and its propeller generates a power of 224 KW (224 kilowatts or 300 hp). Assuming no air drag and full, constant power, calculate the time it takes the Cessna to reach the takeoff speed. 2.

Consider a ball of mass 0.110 kg being spun in a horizontal circle of radius r-0.50 m, as shown to the right. When the ball reaches an angular velocity (o) of 2.00 rad/s, it is given a constant angular acceleration of a- 2.00 rads. You can assume that the radius of the circular path followed by the ball remains constant during this acceleration. After precisely 3.00 seconds of this angular acceleration, the ball breaks off the string (a) In what...
