As a space probe approaching the planet Venus on a parabolic trajec- tory 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) the velocity of the probe as it approaches A, (b) the decrease in velocity required to insert it into the circular orbit. B 280 km

Determine the time needed for the space probe of Prob. 12.100 to travel from B to C.
Reference to Problem 12.100:

As a space probe approaching the planet Venus on a parabolic trajec-
tory 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) the velocity of the probe as it approaches A, (b) the decrease in
velocity required to insert it into the circular orbit.
