A car sitting at a red light begins to accelerate at 2 m/s^2 when the light turns green. It continues with this acceleration until it reaches a speed of 20 m/sIt then travels at this speed for another few minutes. How far does the car travel in the first 35 s after the light changes to green? Express your answer in meters to one significant figure
