Solve the below problem:
Q: During a flyby of the earth, the velocity of a spacecraft is 6.5 mi/s as it reaches its minimum altitude of 620 mi above the surface at point O. At point B the spacecraft is observed to have an altitude of 5200 mi. Assuming that the trajectory of the spacecraft is parabolic, determine its speed at
(a) Point A,
(b) PointB.
