A special airport truck is used to push a heavy airliner away from the terminal. The truck pushes with a force of 4250 N for a distance of 210 m. Calculate the mechanical work done by the truck.

When a light bulb shines, it gives off light energy and energy. a. heat b. potential c. chemical d. electrical

An object resting on a table weighs 100 n. with what force is the object pushing on the table? with what force is the table pushing on the object? explain how you got your answer.

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
