Homework Equations
The Attempt at a Solution
I have the right answer because it is obvious, but I wanted to practice working this out regardless, and I have something slightly different for hmax.
First, I found the y-component of velocity to be:
[itex]V_{o}sin\theta_{o} - 9.8t[/itex]
It follows that at the highest point, that this is equal to 0. So I set it equal to 0 and solved for t.
[itex]t = \frac{V_{o}sin\theta_{o}}{9.8}[/itex]
Integrating my y velocity gives y position:
[itex]y(t) = (V_{o}sin\theta_{o})t - 4.9t^{2}[/itex]
And solving for our time gives me:
[itex]h_{max} = V_{o}sin\theta_{o}(\frac{V_{o}sin\theta_{o}}{9.8}) - 4.9(\frac{V_{o}sin\theta_{o}}{9.8})^{2}[/itex]
Where did I go wrong?
Thanks!
EDIT nevermind! They are the same, just had to do some algebra.
