Statement of a problem № 10348


A 1400-kg automobile starts from rest and travels 400 m during a performance test. The motion of the automobile is defined by the relation a = 3.6e-0.0005x, where a and x are expressed in m/s2 and meters, respectively. The magnitude of the aerodynamic drag is D = 0.35v2, where D and v are expressed in newtons and m/s, respectively. Determine the power dissipated by the aerodynamic drag when (a) x = 200m, (b) x = 400m
