In a football game a kicker attempts a field goal. The ball remains in contact with the kicker's foot for 0.0442 s, during which time it experiences an acceleration of 231 m/s2. The ball is launched at an angle of 55.0° above the ground. Determine the (a) horizontal and (b) vertical components of the launch velocity.

V = Vo + a*t = 0 + 231*0.0442 = 10.21 m/s.
a. V*Cos A = 10.21*Cos55 = 5.86 m/s.
b. 10.21*sin55 = 8.36 m/s.
