A tracking radar lies in the vertical plane of the path of a rocket which is coasting in unpowered flight above the atmosphere. For the instant when e = 30°, the tracking data give r 25x104 ft, v, = 4000 ft/sec, and w = 0.80 deg/sec. The acceleration of the rocket is due only to gravitational attraction and for its particular altitude is 31.4 ft/sec? vertically down. For these conditions determine the velocity of the rocket v, the acceleration of r a, and angular acceleration a.
