A car takes 11 s to go from v=0m/s to v = 22 m/s at constant acceleration.
If you wish to find the distance traveled using the equation d=1/2at2, what value should you use for a?
Express your answer to two significant figures and include the appropriate units.
please help me on the units

think about it. If it takes 11 seconds for the speed to go from 0 to 22, clearly, the speed grows by 2 each second.
So, a = (2m/s)/s = 2 m/s^2
So, a = (2m/s)/s = 2 m/s^2
