The kicker on a football team can give the ball an initial speed of 26.2 m/s. If he is to score a field goal from a point 42.2 m in front of goalposts whose horizontal bar is 3.75 m above the ground, what is the minimum angle above the horizontal he must kick the ball? I was suppose to calculate the minimum and maximum angles. I got 24.3 and 70.8. I set up this equation: xf=xi+vi*cos(theta)t yf=yi+vi*sin(theta)t+4.9t^2 if you solve x time, and then sub it in, it comes out to yf=yi+tan(theta)x+(4.9x^2/v^2)tan^2(theta) 3.75=0+tan(theta)42.2+(4.9(42.2)^2/26.2^2)tan^2(theta) I'm not sure where I'm making the error. I think I did this right, we were told to use the quadratic formula and treat the tan as variables. I'm not really sure what I did after that however.
