One of the equations below represents the height h in feet of a thrown baseball as it changes over time t in seconds. The ball starts at about shoulder height, rises to a maximum, and then falls to the ground.
`h=16t^{2}+40t\ +\ 4`
`h=-16t^{2}+40t\ +4`
`h=16t`
`h=16^{t}\ +\ 4`
Which of these equations is a reasonable model for the given situation? Explain your choice.
