As a space probe approaching the planet Venus on a parabolic trajectory reaches Point A closest to the planet, its velocity is decreased to insert it into a circular orbit. Knowing that the mass and the radius of Venus are 4.87 1024 kg and 6052 km, respectively, determine (a) if the velocity of the probe as it approaches A, (b) if the velocity is decreased by AV, determine to type of trajectory of the space probe. B C 280 km A VENUS: G = 66.73 10-12 m/kg s
