Suppose a truck of mass 1800.0 kg is moving on a road under the influence of 2400.0 N forward forces and 400.0 N of resistive force due to air. How can you estimate net force acting on it, acceleration of the truck? If it starts from rest how much time take, to travel 400.0 m distance? Increase in mass of truck, how it changes acceleration of it without change in external force on it? For motion of truck which Newton's law best suited? Why?
