An object with mass m is initially at rest at the origin z 0 . At time t 0 it starts to accelerate with a changing aceleration along the +z direction. At time t = T it is at the point z-ST and its speed is measured as e(T)-vr . 5. If the foroe accelerating the object is of the form F() - Fo (1-)for SS T, what is the power supplied by the force at acoerating the object is...
