In a football game a kicker attempts a field goal. The ball remains in contact with the kicker's foot for 0.050 s during which time it experiences an acceleration of 390 m/s2. The ball is launched at an angle of 54° above the ground. Determine the horizontal and vertical components of the launch velocity.

vx = ? m/s
vy = ? m/s

I think this should be in the homework section.

a = \frac{v - v_o}{t}
390m/s^2 = \frac{v - 0m/s}{0.050s}

I think you know how to do the rest. If you dont, ask away.

Personally, I wouldn't trust an answer given by anyone stupid enough to fall for that!
