A car is moving at 10 m/s squared.

a) how long does the car take to reach a speed of 25 m/s?

b) how far does it go during this period?

Two very simple formulas:

(1) $v=at$

(2) $x = \frac12 at^2$

Just plug into the first equation to solve for t, then plug that into the second equation to solve for x.
