The satellite is required to move such that its centre ofmass, G, has a linear acceleration of 1.5 m/s in a direction perpendicular to the satellite (rod), and ithas an angular acceleration of 2 rad/s about an axis perpendicular to both the satellite and to thedirection of the linear acceleration of G. Find a single thrust vector (force) that will cause this, andwhere on the satellite this must be applied.Hint: Draw a free-body diagram of the satellite (rod), clearly showing the thrust vector, linearacceleration, and angular acceleration. Due to Newton's 2nd law, the thrust vector must act in thesame direction as the linear acceleration.
