Homework Statement
This problem out of Halliday and Resnick is stumping me. A kicker can kick the ball with an initial velocity of 25 m/sec. The ball is 50 m from a 3.44 m high goal post.
Homework Equations
I have the range equation and the Path equations for a trajectory.
The Attempt at a Solution
The Range equation doesn't seem to help since it only will provide me ranges for various angles. I can easily write the parabolic path equation but I can't crack the math that gets me back to two angles (max and min ). y = (tan θ) X - gX^2/2(Vcos θ)^2
