*Newton's Three Laws and me

I am a soccer player, swimmer, and shopper.

1)If I kick soccer ball the ball will keep going forever until it hits the ball.
2) Beginning of shopping, shopping cart is very easy to push but after 10 mins it starts get harder. Full of shopping cart is harder for push than the empty shopping cart because of mass differences.
3)Whenever I dive off of a diving board, I push down on the springboard. This board springs back and forces me into the air.
