A football is kicked 65 m. If the ball is in the air for 4.3 s, find its horizontal velocity vx. Enter m/s as unit and use g = 10. m/s2.
What is its initial vertical velocity vy? Enter m/s as unit.
With what initial speed was the football kicked? Enter m/s as unit.

d = Vx*t = 65 m.
Vx*4.3 = 65
Vx = 15.1 m/s.
