A punted football is observed to have velocity components vhorizontal = 19 m/s to the right and vvertical = 3.25 m/s directed downward at a height h = 2.9 m above the ground. Use a Cartesian coordinate system with the origin located on the ground at the position the football was punted and assume it encountered no air resistance.
Determine the football's initial horizontal velocity magnitude v0x in terms of vhorizontal, vvertical, g, and h.
Calculate the time, t in seconds, the football moved between being punted and observed.
