1. A football kicker can give the ball an initial speed of 26 m/s. He is 47 m from the goalpost which has a crossbar 2.69 m high. (a) What is the smallest angle of elevation that he can kick the football and score a field goal? 1° (b) What is the largest angle of elevation that he can kick the football and score a field goal? 2° 2. x-xo=(vocos(theta))t y-yo = (v0sin(theta))t-(1/2)gt^2 vy=vosin(theta)-gt vy^2=(vosin(theta))^2-2g(delta y) delta y = (tan(theta))(delta x) -(g(delta x)^2)/(2*(vocos(theta))^2) v^2=v0^2-2g(y-y0) 3. I honestly have no idea how to solve this. I tried to plug my values into the equation v^2=v0^2-2g(y-y0) to get some idea of what the velocity at the goal would be, but I'm not even sure if I need that information or what to do afterwards. Please help give me some direction.
