Hi, a contact of mine works with a school for the blind in Africa, she is looking to source some football equipment for playing blind football. I understand there is a customised ball which makes a sound for player’s to follow. Any ideas where she can buy these ?

A football player kicks a 0.41-kg football initially at rest; and the ball flies through the air. If the kicker’s foot was in contact with the ball for 0.51 s and the ball’s initial speed after the collision is 21 m/s, what was the magnitude of the average force on the football?

My son is a junior, soon to be senior, football player. He has great size 6′3″ and 245 lbs, and a great motor. My problem is, becuase of a military move, he missed his entire junior year of football. I know the junior year is the most important as far as generating interest from colleges, and he is behind the eightball. How can I contact colleges to help generate interest in him?
