The spacecraft P is in the elliptical orbit shown. At the instant represented, its speed is v

Question:

The spacecraft P is in the elliptical orbit shown. At the instant represented, its speed is v = 13,244 ft /sec. Determine the corresponding values of r˙, θ˙, r¨, and θ¨. Use g = 32.23 ft /sec² as the acceleration of gravity on the surface of the earth and R = 3959 mi as the radius of the earth.
