# A car, which is accelerating uniformly from rest, travels a distance of 28.5 m in the tenth second of its motion. What is its acceleration?

##
The only thing I can think of is to use v=u+at, where u = 0 m/s, t = 10 s and v = 28.5 m/s. But the velocity is constantly increasing so the final velocity value is incorrect. Hmm.

The acceleration is

#### Explanation:

Let the acceleration of the car be

To find the distance traveled in the 10th second, we have to subtract the total distance traveled in
