It increasesquadratically with velocity (essentially because the amount of air yourun into increases with v and so does the amount of force you mustexert on each small volume of air). ThusConsider a vehicle moving with constant velocity v. Find the power dissipated by form drag.Express your answer in terms of Ca, A, and speed v.Farag = Ca Av?,» View Available Hint(s)where A is the cross-sectional area of the vehicle and Ca is called thecoefficient of drag.P =Submit

A section of a roller coaster is designed like the picture below. A roller coaster car with a mass of 230.0kg is released from rest at the top of the hill at Point A to begin the ride. Assume that the reference level is set to the ground, and that energy is not lost to other forms (i.e. heat, sound, etc.). What is the total mechanical energy of this roller coaster car (at any point)?
