Problem

After subjecting a car design to wind-tunnel testing, the students estimate that the tangential component of the car’s acceleration will be at = 0.6 – 0.002v2 m/s2, where v is the car's velocity in m/s. If the car starts from rest at A. what are its velocity and acceleration in terms it normal and tangential components when it reaches B?
