A speeder passes a stationary police officer at a constant speed of 45 m/s. The police officer immediately begins pursuit with a constant acceleration of 5 m/s^2. Assuming the speeder
maintains their original velocity determine:
a) The time required for the officer to catch the speeder in seconds(Number only).
[Select ]
b) The velocity of the officer at the time of intercept in m/s (Number only).
[ Select]

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.
