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.

Question

A punted football is observed to have velocity components vhorizontal = 19.5 m/s to the right and vvertical = 4.75 m/s directed downward at a height h = 1 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.

1.Determine the football�s initial horizontal velocity magnitude v0x in terms of vhorizontalvverticalg, and h.

2.Calculate the time, t in seconds, the football moved between being punted and observed
