At 0.5 of its maximum height, the speed of a projectile is 0.75 of its initial speed. What was its launch angle?
Not sure here, but:
v^2 - vo^2 = 2as [maximum height]
Ay = Asin(theta) [y-component]
The Attempt at a Solution
I didn't get very far, but:
vo = vo
v = 0.75 vo
0.75vo^2 - vo^2 = (2)(-9.8)s
-0.25vo^2 = -19.6s
vo^2 = 784s
I'm stuck from here on, should I try to find the y-component for this?
[Also I'm an almost total beginner at Physics, excuse me if I'm totally wrong].
Any help would be greatly appreciated. Thanks everyone!
