Let's examine over the next few questions an nfl kick as described in the 3rd law video. the announcer claimed that the ball is struck with "almost a ton of force." first of all, phrases like "almost a ton" drive physics people crazy. give me a number! so let's guess-timate 1900 lbs of force. convert that to newtons. (you can always just google this one)
