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

What I'm supposed to do is to rearrange the this formula -16t^2+Vt+h and solve it for V.

V= Initial Velocity t= time (throwing the ball in a parabolic arc) h= height

I know what the height is and it is 6ft. I also have the time which is 2.03 seconds.

How do I rearrange for V? I got an answer but I'm not sure and doubting if it is correct.

2. Relevant equations

-16t^2+Vt+h

-16t^2+Vt+6 (if you plug in the height.)

3. The attempt at a solution

-16t^2+Vt+6 What I started with

-16t^2+Vt= -6 Subtracted 6 to the other side

Vt= -6+16t^2 Added -16t^2 to both sides.

V= (-6/t)+16t Divided both sides (every term) by t. This is my answer so far.

I have no idea if I'm correct or not and I have the feeling I'm not. Please help, i'm in US grade 9.
