A geologic study is being conducted on Mars (rMars = 3.396E3 km) using a surface rover and an orbiter (rOrbiter = 20E3 km). During the study the orbiter will release (v = 0) a projectile that will impact the Martian surface exposing the subsoil. Determine the speed of the projectile when it strikes the surface if the acceleration due to gravity is a = -42.828E3/r^2 km/s^2 . where r is the distance from the center of Mars. (km/s)
