A tracking radar lies in the vertical plane of the path of arocket. For the instant when the angle θ = 300, thetracking data give r = 200,000 ft, dr/dt= ṙ = 4000 ft / sec, anddθ/dt= θ̇ = 0.9 deg / sec. The acceleration of therocket is due only to gravitational attraction g = 31.2 ft / sec2vertical down. For these conditions determinea) The velocity v of the rocket.b) The values of d^2r/dt^2 = r̈, and d^2θ/dt2 = θ̈
