A car starts from a traffic light and accelerates at 0.2 m/s^2 until nit reaches its cruising speed. It drives at the cruising speed and starts slowing down 500m before the next traffic light where it comes to a stop. The traffic lights are 6 km apart and the car covers the distance within 6 min. Calculate the cruising speed.
