A.) The small spherical planet called "Glob" has a mass of 7.96+18 kg anda radius of 66200 m. An astronaut on the surface of Glob throws arock straight up. The rock reaches a maximum height of 1200 m,above the surface of the planet, before it falls back down. Whatwas the initial speed of the rock as it left the astronaut's hand?(Glob has no atmosphere, so no energy is lost to air friction.) (G= 6.67 x 10-11Nm2/kg2)
B.) A 26.0 kg satellite is in a circular orbit with a radius of 1.60×105 m around the planet Glob. Calculate the speed of the satellite. in m/s
