Trajectory, "does it clear a certain height" problem help! 1. The problem statement, all variables and given/known data A place kicker must kick a football from a point 45.5 m from the goal, and the ball must clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground with a speed of 19.0 m/s at an angle of 48.0° to the horizontal. By how much does the ball clear or fall short of clearing the crossbar? 2. Relevant equations Dy = distance in y = Voy *t -1/2gt^2 Dx = ~~~ x = Vox * t Vox = initial velocity in x Voy = ~~~~ y 3. The attempt at a solution I tried to express Y in terms of x... since x = Vox * t .... t = x / Vox then Dy = Voy(x) / Vox - 4.9 (x^2/Vox^2) assume gravity's 9.8 Plug in 45.5 m for x Voy = 14.12 m/s Vox = 12.71 m/s Dy = -12.23 m So when the ball is 45.5 m long, its 12.23m underground. which means the ball is 12.23 - 3.05 = 9.18m short of crossing the bar. Idk... seems simple enough but apprently the answer's wrong. Thanks alot for your help!
