find the mass of Planet X.   b) Suppose that at the moment the spacecraft reaches its maximum height, a rocket thruster briefly turns on to give the spacecraft a tangential velocity so that it can move in a circular orbit around Planet X. What tangential velocity would the spacecraft need in order to move in a circular orbit at an altitude of 4.80km above Planet X's surface?

A spacecraft is launched from the surface of a mystery planet, Planet X. Suppose that the
spacecraft reaches a maximum height of 4.80 km after being projected straight upward with an
initial speed of 134 m/s. Suppose the radius of planet X is 1860 km.
