(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A projectile is shot straight up from the earth's surface at a speed of 1.40×10^4 . How high does it go?

2. Relevant equations

potential energy is given by (GM(1)M(2))/R

3. The attempt at a solution

I attempted to solve this using energy conservation equation and solving for r which I thought would be the radius of the earth plus the distance traveled by the projectile. By subtracting the radius I thought I would get the distance traveled but my answer is wrong can someone help please
