4) A spacecraft designed for Martian impact is on a course heading directly toward the center of the planet. If the spacecraft is 10,000 km from the surface of the planet and is traveling at a relative speed of 20,000 km/hr, compute the impact velocity, v. The gravitational acceleration at the surface of Mars is g = 3.73 m/s^2, and the planet has a diameter of 6800 km. Neglect atmospheric resistance. ANS. V₂ = 7055 m/s = 25,400 km/hr FBD AND KINEMATICS DIAGRAMS
