# Question: A tracking radar lies in the vertical plane of the path of a rocket that is coasting in unpowered flight above the atmosphere. For the instant when θ=30°, the tracking data give r=25(104) ft, r=4000 ft/sec, and θ=0.80 deg/sec. The acceleration of the rocket is due only to gravitational attraction and for its particular altitude is 31.4 ft/sec2 vertically down. For these conditions determine the velocity v of the rocket and the values of r” and θ”. -Free Course Hero Question Answer.

Question Description: A tracking radar lies in the vertical plane of the path of a rocket that is coasting in unpowered flight above the atmosphere. For the instant when **θ**=30°, the tracking data give r=25(104) ft, r=4000 ft/sec, and **θ**=0.80 deg/sec. The acceleration of the rocket is due only to gravitational attraction and for its particular altitude is 31.4 ft/sec2 vertically down. For these conditions determine the velocity v of the rocket and the values of r” and **θ**“.
