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..
