A rocket is tracked by radar from its launching point A. When it is 10 seconds into its flight, the following radar measurements are recorded: r=2200m, r'=500m/s, r"=4.66m/s^2, theta=22 deg, theta'=0.0788 rad/s, and theta"=-0.0341 rad/s^2. For this instant determine the angle beta between the horizontal and the direction of the trajectory of the rocket and find the magnitudes of its velocity v and acceleration a.
