Question

A punter kicks a football. Its height, h(t), in metres, t seconds after the kick is given by the equationh (t)=−4.9t2+18.24t+0.8. The height of an approaching blocker’s hands is modelled by the equationg (t)=−1.43t+4.26, using the same t. Can the blocker knock down the punt.

Answer 1

Answer:

Yes

Step-by-step explanation:

−4.9t² + 18.24t + 0.8 = −1.43t + 4.26

-4.9t² + 19.67t - 3.46 = 0

4.9t² - 19.67t + 3.46 = 0

Using quadratic formula:

t = [19.67 +/- sqrt(319.0929l)]/9.8

t = (19.67 +/- 17.8631716109)/9.8

t = 3.8299154705, 0.1843702438

Since the two can be at the same height at the same time, the blocker can knock down the punt
