So today we will be going back to the topic of football and looking at another aspect in the game. We will be looking at the kinematics of a quarterback throwing a football. So when you see a quarterback throw a football, how fast do you think they need to throw it? You can use kinematics to find that. So being the quarterback, you guesstimate that he will run 50 meters in 6 seconds. You know that halfway, the velocity in the vertical direction is 0 and at the start, it is also 0. So knowing that you can find the horizontal initial velocity with the distance = 50, the acceleration 0, the time 6, and final velocity is not needed. Using the equation Δx = Vo(t) + .5at^2 to get the initial velocity. And also doing the same for the vertical initial velocity, you now have the components of velocity. Set up a right triangle and use Pythagoras thereom to find the velocity of the football the quarterback would need to throw. I don't think a quarterback has enough time to do that all in his head but you never know. That's our second time visiting the physics of football. Tune in next time for more exciting physics work.
