Radius of curvature of trajectory

[Dusty912]

Homework Statement

a golfer hits a golf ball so that it has an initial velocity of 165mph and 12 degrees above the horizon. I already know the radius of curvature when the ball is hit. but my question is, will the radius be that same when it hits the ground?

Homework Equations

a_n=v²/ρ

The Attempt at a Solution

the radius of curvature when the ball is hit is 1859ft, since the velocity will be the same when it hits the ground except for it being 12 degrees BELOW the horizon, the radius should be the same right?

Right.
