Homework Statement
Show that for a projectile d^2 (v^2)/dt^2 = 2g^2
Homework Equations
The Attempt at a Solution
Since we are only dealing with the y component for this. 2nd derivative would be 2. But since gravity acts on it then d^2 (v^2)/dt^2 = 2g. I don't get how to get to 2g^2. Can someone help me please.
