How far will a car travel before coming to rest?

[chris783]

A car is decelerating uniformly. Its velocity changes from 30m/s to 15m/s in 75m. How much further will it travel before it comes to rest?

- Please, i need a detail answer. Thanks!

What equation do you think is relevant to this question?

 

[chris783]

v^2=u^2 + 2as, i think this equation is relevant to the question.

That's the one you need. Apply it twice: once to find the acceleration and again to find the final distance.
