A 3000-lb automobile starts from rest and travels 1200 ft during a performance test. The motion of the automobile is defined by the relation a = 11e-0.0005x , where a and x are expressed in ft/s2 and feet, respectively. The magnitude of the aerodynamic drag is D = 0.01v2, where D and e are expressed in lb and ft/s, respectively. Determine the power dissipated by the aerodynamic drag when
(a) x = 600 ft,
(b) x = 1200 ft.
