A 5​-gram ​[g] rubber ball is released from a height of 8 meters​ [m] above a flat surface on the moon. Gravitational acceleration on the moon is 1.62 meters per second squared ​[m/s2​]. Assume that no energy is lost from frictional drag. What is the​ velocity, in units of meters per second​ [m/s], of the rubber ball the instant before it strikes the flat​ surface?
