Part a determine the footballs initial horizontal velocity

A punted football is observed to have velocity components vhorizontal = 17 m/s to the right and vvertical = 2.5 m/s directed downward at a height h = 1.8 m above the ground. Use a Cartesian coordinate system with the origin located at the position the football was punted and assume it encountered no air resistance. Assume the x axis is located at h = 0.

Part (a) Determine the football's initial horizontal velocity magnitude v0x in terms of vhorizontal, vvertical, g, and h.

Part (b) Calculate the time, t in seconds, the football moved between being punted and observed.
