Homework Statement
There is an image but I will reiterate my problem.
The writer is solving for t. Okay, easy enough.
Homework Equations
y-y0 = v0 t + 1/2 a t^2
Textbook says
t = sqrt( (2(y-y0) - 2 v0) / a )
The Attempt at a Solution
Shouldn't it be
t = sqrt( (2(y-y0) - 2 v0 t) / a )
Let's take it slow.
Multiply both sides by two.
2(y-y0) = 2 v0 t + a t^2
Bring (2 v0 t) to left side.
2(y-y0) - 2 v0 t = a t^2
Divide both sides by a.
(2(y-y0) - 2 v0 t) / a = t^2
Sqrt both sides.
t = sqrt( (2(y-y0) - 2 v0 t) / a )
This really bugs me.
