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 340 m/s2. The ball is launched at an angle of 48° above the ground. Determine the horizontal and vertical components of the launch velocity.
Vx=________m/s
Vy=________m/s
