You are stopped at a red light. The split second the light turns green, you begin to accelerate at a rate of 2 m/s2 until you reach a speed of 11 m/s (this is about 25 mph). How far have you traveled during this time? Hint: be sure you can solve this with a velocity vs time graph!!!

Scott · Answer

you accelerate for 5.5 s (11 m/s / 2 m/s^2) your average speed is ... (0 + 11 m/s) / 2 distance is ... speed * time
