A punter in a football game kicks a ball from the goal 60° from the horizontal at 25 m/s. What is the hang time afthe punt, and how far down field does the ball land?
We get the time taken to reach the maximum height by using the vertical component of the velocity:
By inference the return to earth will take the same time, assuming a level playing field.
The horizontal component of velocity is constant so we get:
Distance = speed x time
