Question

4. A punter in a football game kicks a ball from the goal line at 60.00 from the horizontal at

25.0 m/s.
a. What is the hang time of the punt?
b. How far down field does the ball land?

Answer 1

Step-by-step explanation:

Step-by-step explanation:

(a)

We get the time taken to reach the maximum height by using the vertical component of the velocity:

v=u+at

∴ 0=25sin60−9.8t

∴ t=21.65/9.8=2.21s

By inference the return to earth will take the same time, assuming a level playing field.

∴ total time in flight =2×2.21=4.42s

(b)

The horizontal component of velocity is constant so we get:

Distance = speed x time=25cos60×4.42=55.25m
