8. Fig. 1.1 shows three forces acting on an object of mass 0.5 kg. All three forces act rough the centre of mass of the object. 9.0N Fig. 1.1 centre of mass 3.0N 4.0N Calculate (i) the magnitude and direction of the resultant force on the object, magnitude = direction (ii) the magnitude of the acceleration of the object. left [2] acceleration =.
