Question: An object of mass 0.5 moves with position function r(t) =. 1(a). Find the speed of this object. (b). Find the force vector acting on

An object of mass 0.5 moves with position function r(t) =. 1(a). Find the speed of this object. (b). Find the force vector acting on this object at time t 2 7T. Show that it points from the object towards the origin. That is, show that it is in the same direction as the vector from the object to (0, 0, 0). (c). Find the object 's tangential and normal components of acceleration at time t
