A soccer ball has a mass of 0.45 kg when it is kicked from rest by a foot that has a mass of 6.1 kg.  The coefficient of restitution between the ball and the foot is 0.72 and the final velocity of the ball just as it leaves the foot during the shot is 25.1 m/s. What is the velocity of the foot in meters per second (m/s) just as it makes contact with the ball during the shot?
