A block of mass 1 kg lies on a horizontal surface on a truck.The coefficient of static frction between the block and surface is 0.6.If the acceleration of the truck is 5 m/s^2,the frictional force acting on the block is......... N.The question can be solved in two ways ,by applying the formula f=mu*M*g or by drawing fbd and equalising forces.which method is most suitable?? both situation give different answers.
