A punter wants to kick a football so that the football has a total flight time of 4.70s and lands 57.0m away (measured along the ground). Neglect drag and the initial height of the football.
- How long does the football need to rise?
- What height will the football reach?
- With what speed does the punter need to kick the football? (vertical component, horizontal component, and vector magnitude)
- At what angle (θ), with the horizontal, does the punter need to kick the football?

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
