Sloane kicked a soccer ball at a speed of 56 feet per second. If the ball never leaves the ground, then it can be represented by

aksik [14]

Answer:

Third option: $t=3.5\ seconds$

Step-by-step explanation:

Given the function:

$H(t)=-16t^2 +56t$

Since the ball never leaves the ground, you need to substitute $H(t)= 0$ in the function in order to determine the time the soccer ball traveled:

$0=-16t^2 +56t$

Factorizing, you get:

$0=-8t(2t-7)$

Then:

$0=-8t\\\\t=0\ seconds\\\\\\\\0=2t-7\\\\7=2t\\\\t=3.5\ seconds$

Therefore the time the ball traveled was:

$t=3.5\ seconds$
