A red car and a blue car are moving down the road. The two cars are just alike other than the color. Which car has the most kinetic energy? A. The one that is moving slower B. The one that is moving downhill C. The one that is moving faster D. The won that is moving uphill

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.
