Problem
A toy car of mass 2.0kg is placed on a smooth horizontal track. Three horizontal pulls act simultaneously on the car: 5N towards the east, 3N towards the west and 4N towards the east. The car is initially at rest. Answer the following questions.
(i) Determine the magnitude and direction of the resultant horizontal force acting on the car.
(ii) Using your result from part (i), find the acceleration produced in the car.
(iii) Calculate the speed attained by the car after 6s.
(iv) How far does the car travel in this time interval?
