# Question: Shown in Fig 4 31 are the front and rear wings

Shown in Fig. 4.31 are the front and rear wings of an Indy racing car.

These wings generate down force, which is the vertical downward force produced by the air moving over the car. Why is such a down force desired? An Indy car can create a down force equal to twice its weight. Why not simply make the cars heavier?

(a) We commonly say that friction opposes motion. Yet when we walk, the frictional force is in the direction of our motion (Fig. 4.17). Is there an inconsistency in terms of Newton’s second law? Explain. (b) What effects ...The following is an old trick (Fig. 4.28). If a tablecloth is yanked out very quickly, the dishes on it will barely move. Why? A force acts on a 1.5-kg, mass, giving it an acceleration of 3.0 m/s2. (a) If the same force acts on a 2.5-kg mass, what acceleration would be produced? (b) What is the magnitude of the force? A student weighing 800 N crouches on a scale and suddenly springs vertically upward. His roommate notices that the scale reads 900 N momentarily just as he leaves the scale. With what acceleration does he leave the scale? In Exercise 2, if the 35-N force acted downward at an angle of 40° relative to the horizontal, what would be the acceleration in this case?Post your question
