## Homework Statement

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?

## Homework Equations

vx0=v0cos(angle)

vy0=v0sin (angle)

t=vy0/g

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

x=vx0*t

## 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.
