An object in space is observed to have an altitude of 2209 km, a velocity of 7000 m/s and an elevation angle (φ ) of 40o . (a) Give a complete description of the trajectory. (b) Is there anything special or different about this trajectory? (c) Find v,θ , φ when r = 6.378 x 10 6 m. Sketch the trajectory and locate this point.
