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

Two footballs, A and B, are kicked from level ground with identical initial speeds, but with θA greater than θB.

Which football reaches a higher elevation?

Which football travels farther?

Which football stays in the air longer, i.e., has the greater hang time?

Which football has the greater horizontal component of velocity?

2. Relevant equations

vx0=v0cos(angle)

vy0=v0sin (angle)

t=vy0/g

y=((vy0^2)-vy^2)/g

x=vx0*t

3. The attempt at a solution

I thought the answers were Football A, Football B, Football A, and then Football B, but these were wrong. I did a plug-in for this problem and I used 60 degrees for Angle A and 50 for Angle B with an initial velocity of 20 m/s. When I did all of the calculations out, I got the results I said above.
