The problem that follow involve straight-line motion. The time t is in seconds unless otherwise stated.

Problem

The airplane flies in a straight line at 400 rni/h. The radius of its propeller is 5 ft, and the propeller turns at 2000 rpm in the counterclockwise direction when seen from the front of the airplane. Determine the velocity and acceleration of a point on the tip of the propeller in terms of cylindrical coordinates. (Let the z axis be oriented as shown in the figure.)
