A dragster accelerates from rest down a road of length d = 400.0 m. In the absence of any friction the dragster has a constant acceleration of a = 22.6 m/s² in the direction of motion, and its mass is m = 905 kg. Assume the dragster is moving in the positive horizontal direction.

part. A Assuming there is no rolling friction, write an expression for the amount of net work done on the dragster, W_d, during the run, in terms of the given quantities.

part b. Now consider the existence of rolling friction, which causes a total resistive force with magnitude F_r on the dragster. What Is the expression for the work done by this force over a distance d.

part c. Give an expression for the total kinetic energy of the dragster, E_d, in the presence of rolling friction after it travels a distance d.

part d. What is the dragster's final speed, in meters per second, assuming F_r = 1000 N?
