1. The problem statement, all variables and given/known data A football kicker can give the ball an initial speed of 25 m/s. what are the least and greatest angles of elevation at which he can kick the ball to score a field goal from a point 50m in front of the goalposts whose horizontal bar is 3.44m above the ground? 2. Relevant equations I really don't know what to do 3. The attempt at a solution I figured I could write V0tcosX=50 and V0tsinX-.5gt2=3.44 Then I tried to find t in terms of X and got t=50/(V0cosX) Then I plugged that in to the other equation and I got 50tanX-12250/cos2X-2150=0 I thought then I could find the zeros and that would be my answer but it doesn't seem to be working... I can't figure out why. Maybe I totally missed the answer but either way I still need help lol. Thanks.
