## Homework Statement

A runner exerts a constant force to accelerate from rest to 2.0 m/s over a distance of 12 m.

Assuming the runner can keep up the same force, what total distance would be needed to ac-

celerate up from rest to 3.0 m/s?

## Homework Equations

none given.

## The Attempt at a Solution

The answer to the problem is 27. After quite some time spent thinking I tried solving first part for time using x= 1/2 vt and then plugging it into 2nd part. but that gives time as 12 and 2nd x as 18 so wrong. Dunno how to solve it
