Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I need help; here's the question:

"A ball is launched as a projectile with initial speed v at an angle theta above the horizontal. Using conservation of energy, find the maximum height (hmax) of the ball's flight. Express your answer in terms of v, g, and theta."

I tried hmax = ((1/2)*(v^2))/(g) which didn't work; I then realized that it's not a straight throw the ball upward question.

I tried hmax = ((1/2)*((v)*sin(theta)))^2))/(g) and it didn't worked either; I thought I might have mistyped so I answered that question again, with the same answer.

I then got very frustrated and impulsive since I had only 2 more trys, so I tried hmax = ((1/2)*(vcos(theta)^2))/(g), which is obviously wrong and didn't work.

Now, I have only one more attempt remaining, please help.

Thanks in advance
