Problem
A 5kg box rests on a frictionless horizontal surface. Two horizontal forces act simultaneously on the box: 20N due east and 15N due north.
(i) Calculate the magnitude of the resultant force acting on the box.
(ii) Determine the magnitude and direction of the acceleration of the box.
(iii) If the same resultant force acts on another box of mass 10kg placed on the same surface, compute the magnitude of its acceleration.
