4. 30N force is applied on 6 kg object which is at rest on a smooth horizontal table. Determine the normal force acting on the object and its acceleration for following cases. I. Applied force is horizontal. II. 30N force is directed 30 above horizontal III. 30 N force is directed 30 below horizontal. 5. An object is thrown vertically upward with speed of 20 m/s. Determine its speed at a point halfway to maximum height
