A wheel 2.00 m in diameter lies in a vertical plane androtates about its central axis with a constant angularacceleration of 4.00 rad/s2. The wheel starts at rest att =0, and the radius vector of a certain point P on therim makes an angle of 57.38 with the horizontal at thistime. At t 5 2.00 s, find (a) the angular speed of thewheel and, for point P, (b) thetangential speed, (c) thetotal acceleration, and (d) the angular position.

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.
