You find it takes 190 N of horizontal force to move an unloaded pickup truck along a level road at a speed of 2.4 m/s . You then load up the pickup and pump up its tires so that its total weight increases by 42%while the coefficient of rolling friction decreases by 19%. Now what horizontal force will you need to move the pickup along the same road at the same speed? The speed is low enough that you can ignore air resistance..

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
