Why is a rotated coordinate system used to solve an inclined plane problem?
A) Reduce the number of forces that need to be resolved into their x and y components.
B) To eliminate the need to consider the force of gravity.
C) To align the coordinate axes with the acceleration of the object on the plane.
D) To minimize the number of forces that need to be considered.

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.
