Homework Statement
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.
Homework Equations
x = vt
x = Vot+(1/2)at2
Vf2=Vo2+ax
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/s2
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!
