2/143 The rocket is fired vertically and tracked by the radar station shown. When reaches 60°, other cor- responding measurements give the values r = 30,000 ft, 70 ft/sec², and ė = 0.02 rad/sec. Calculate the magnitudes of the velocity and accel- eration of the rocket at this position. ра Problem 2/143
