2. The acceleration due to gravity of a planet R is a = -g where h g is the acceleration due to gravity on the surface of the planet, R is the radius of the planet, and h is the distance from the center of the planet. " R So Vo s = 200,000km v = 2000m/s The planet is Venus with a radius of 6050 km and our spacecraft is 100 km above the surface with an initial velocity of vo = 37,140 km/hr straight away from the planet. When the spacecraft is 200,000 km from the surface, its velocity is 2000 m/s. Determine the value of g (in m/s), the acceleration due to gravity on the surface of Venus. Neglect the effect of gravity due to the sun or any other planets.
