if a football player passes a football from 4 feet off the ground with an initial velocity of 36 feet per second, how long will it take the football to hit the ground? use the equation h = −16t^2 + 6t + 4. round your answer to the nearest hundredth.
a) 0.72
b) 0.65
c) 0.35
d) 0.27

Option A is correct

Step-by-step explanation:

The given equation is

h = -16t^2+6t+4

When the ball will hit the ground, height h = 0

Putting value of h = 0

0 = -16t^2+6t+4

Now solving to find the value of t

=> -16t^2+6t+4 = 0

Multiply with -1

16t^2-6t-4=0

Using quadratic formula to find value of t

a= 16, b= -6 and c= -4

Putting values,

Since time cannot be negative, so t = 0.721 or 0.72

So, Option A is correct

chase is right because he already been to the swings and he know how far it will be to get there
