QUESTION 2 ITOTAL MARKS: 20)] [10 Marks] Q 2(a) An object rests on a plane parallel to the x-y plane. A 9 N force acting in the z-direction moves this object from the point (6,3,5) to the point (11,1,7), where distance is measured in meters. (a) Determine the force vector (b) Determine the displacement vector (c) Hence, determine the work done by the force on the object. Hint: Remember that work is a scalar quantity!
