Question

Il PauseHeltA punter kicks a football. Its height (h) in meters, t seconds after the lack is given by the equation: 1491 +18.24t +0.8. The height of an approaching blocker's hands is modeled by theequation: -1.43t+ 4.26, using the same time. What time does blocker knock down the football?O A 6.8 secondsB. -1.2 secondsO C 0.18 secondsD. -3.9 seconds

Answer 1

H = -4.9t^2 +18.24t +0.8.

h = -1.43t + 4.26

Then solve H=h

-4.9t^2 +18.24t +0.8 = -1.43t + 4.26

Now rewrite equation

-4.9t^2 + (18.24+1.43)t + (0.8 - 4.26) = 0

-4.9t^2 + 19.67t - 3.46 = 0

Now solve for t

t = 0.1843

Then ANSWER IS

OPTION C) 0.18 seconds
