. An airplane takes off at 10:00am and flies straight at 350 km/hr until 1:00pm. Its velocity then changes to 400 km/hr in the same direction until it lands at 3:30pm. What is its average velocity of the airplane for the entire flight? :)​

Physics

A model airplane with a mass of 0.748 kg is tethered by a wire so that it flies in a circle 30.2 m in radius. The airplane engine provides a net thrust of 0.806 N perpendicular to the tethering wire.

(a) Find the torque the net thrust produces about the center of the circle.

N·m

(b) Find the angular acceleration of the airplane when it is in level flight.

rad/s2

(c) Find the linear acceleration of the airplane tangent to its flight path.

m/s2
