Apply the grid method to each situation that follows.

a. Use Eq. (11.5) to predict the drag force in newtons for an automobile that is traveling at V = 60 mph on a summer day. Assume that the frontal area is 2 m² and the coefficient of drag is C_D = 0.4.

b. Apply Eq. (11.5) to predict the speed in mph of a bicycle rider that is subject to a drag force of 5 lbf on a summer’s day. Assume the frontal area of the rider is A = 0.5 m², and the coefficient of drag is C_D = 0.3.
