A football kicker can give the ball an initial speed of 27 m/s. He is 54 m from the goalpost which has a crossbar 3.37 m high.
(a) What is the largest angle of elevation that he can kick the football and score a field goal?
(b) What is the smaller angle of elevation that he can kick the football and score a field goal?
rf=r0 + vdeltat
The Attempt at a Solution
I'm confused about where to begin this problem ,considering that I don't have time.
Would I do something like:
rf-ri= 27sintheta, but then I would need the change in time, which is not given.
Any thoughts on how to solve this problem?
