Problem

An automobile of mass 1000 kg1000\,\text{kg} moves along a straight, level road. The engine supplies a constant forward force of 2500 N2500\,\text{N} while air resistance and rolling friction together offer 1500 N1500\,\text{N} opposite to the motion. The car starts from rest. Answer the following questions. a. (i) Calculate the acceleration of the car. b. (ii) How far will the car travel in the first 5 s5\,\text{s} of its motion? c. (iii) What will be its speed at the end of 5 s5\,\text{s}?
