A soccer player takes a corner kick, lofting a stationary ball 37.0° above the horizon at 18.0 m/s. If the soccer ball has a mass of 0.425 kg and the player's foot is in contact with it for 5.10 x 10-² s, find the x- and y-components of the soccer ball's change in momentum and the magnitude of the average force exerted by the player's foot on the ball.
