A soccer player kicks the ball toward a goal that is 16.8 m in front of him. The ball leaves his foot at a speed of 16.0 m/s and an angle of 28.0 degrees above the ground. Find the speed of the ball when the goalie catches it in front of the net.

2. Relevant equations

x = vt

x = Vot+(1/2)at^{2}

Vf^{2}=Vo^{2}+ax

3. The attempt at a solution

Vx = (cos 28)(16.0) = 14.1 m/s

Vy = (sin 28) (16.0) = 7.5 m/s

Horizontal

x = 16.8 m

V = 14.1 m/s

Vertical

a = -9.8 m/s^{2}

Vyo = 0 m/s

(V = 7.5 m/s?)

I'm stuck as to where I should go from there or even if I started out correctly.

If you can assist me, I would be very grateful. Thank you!
