Section 1 1. What was the purpose of this research study? To characterize and find the location and magnitude of impacts sustained by football players during a football season. 2. What indpendent and dependent variables were used to accomplish the purpose of this study ? Independent - speed and mass of player dependent - linear acceleration and impact force 3. With the results of this specific study in mind, what strategies might football coaches and players utilize to decrease the probability of head and neck injuries in American Football? They need to teach their player to not impact other players with the top of their head because that is the place that yields the greatest linear acceleration and impact force magnitude. Section 2 1. A runner jogs 2 laps around a 400 meter track in 6 minutes and 40 seconds. He then goes 2 more laps in 3 minutes and 30 seconds before stopping at the point

Unformatted text preview: on the track where he began. What was his average velocity? 2.62m/s 2. What was his displacement? 3. A basketball player dribbles down the court. At one point her velocity was 2.7 m/s, however, 0.4 seconds later, her velocity was 3.9 m/s. What was her acceleration during this time? .3m/s/s 4. During a free kick (the ball is not moving previous to being struck) a soccer ball is kicked upward at a 40 degree angle (relative to the ground) with an initial velocity of 30 m/s. The players foot makes contact with the ball for only .23 seconds.What is the average acceleration the ball experiences while in contact with the foot? 130.4m/s/s 5. Ignoring the effects of air resistance, what is the maximum height that the ball will reach? 45.92m...
