(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Well to sum up the question: a football kicker kicks a ball with 20m/s initial velocity with a 53 degree angle. the goal post is 36m away and is 3.05m tall. does the ball pass the goal post? does the ball approach the crossbar while still rising or falling?

range=36m

acceleration= -9.8 m/s/s

V initial = 20m/s

angle theta= 53 degrees

height of post=3.05m

2. Relevant equations

range= (velocity initial x) multiply (time)

vix (velocity initial x) = vi cos angle theta

viy (velocity initial y) = vi sin angle theta

y=(viy) multiply (time) + 0.5at^2

3. The attempt at a solution

using the above information i found the that the ball crosses the goal post by 0.85meters.

here the problem. i dont know how to do the second part. any and all help will be appreciated thx.
