Hi folks, Need some help on a projectile motion question. 1. The problem statement, all variables and given/known data Given: - a football kicker can give the ball an initial speed of 25m/s - kicker wants to score a field goal 50m in front of goalposts - horizontal bar of goalposts is 3.44m above the ground Question: What are the a.) least and b.) greatest elevation angles at which he can kick the ball to score a field goal? 2. Relevant equations none 3. The attempt at a solution I have done the following: 1.) y = y0 + (v0sinθ)t - 0.5(9.81)t2 so, 3.44 = (25sinθ)t - 4.91t2 2.) x = x0 + (v0cosθ)t so, 50 = (25cosθ)t so, t = 2/cosθ I then substituted eq. 2 into eq. 1, and got the following: 3.44 = 50tanθ - 19.62sec2θ but I am stuck here. Could someone please tell me if I am on the right track? Is there a way to solve the above equation, or am I approaching this in the wrong way? Thanks.
