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

A cannon is fired on another planet straight up at 25 m/s. It reaches a maximum height of 50m. What is the value of the gravitational acceleration?

2. Relevant equations

v = v_i + at

x = .5 (v_i + vt)

3. The attempt at a solution

using the first equation,

a = (v - v_i)/t

a = (0-25)/2

g = -12.5 m/s^2

Where am I going wrong? Thanks
