Q) A driver is driving a car in a circular ring which is 120 m in diameter. At one instant, his total acceleration is 12 m/s2 with a direction of 30° relative to the tangent. a) Determine his radial and tangential acceleration. b) Starting from the state described above and maintaining the same tangential acceleration, how long does he need to perform one complete circuit?
