A soccer player takes a corner kick, lofting a stationary ball 40.0° above the horizon at 20.0 m/s. If the soccer ball has a mass of 0.425 kg and the player's foot is in contact with it for 4.90 ✕ 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. (a) the x- and y-components of the soccer ball's change in momentum (in kg · m/s) Δpx= Δpy= (b) the magnitude of the average force exerted by the player's foot on the ball (in N)

Question
A soccer player takes a corner kick, lofting a stationary ball 40.0° above the horizon at 20.0 m/s. If the soccer ball has a mass of 0.425 kg and the player's foot is in contact with it for 4.90 ✕ 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.
(a)
the x- and y-components of the soccer ball's change in momentum (in kg · m/s)
Δpx=
Δpy=
(b)
the magnitude of the average force exerted by the player's foot on the ball (in N)
