A dragster starts from rest and accelerates down a track. Each tire has a radius of 0.320 m and rolls without slipping. At a distance of 400 m, the angular speed of the wheels is 275 rad/s. Determine
(a) the linear speed of the dragster and
(b) the magnitude of the angular acceleration of its wheels.
