A ball is thrown upward from a height of 15 ft with an initial velocity of 5 ft/s. Use the equation h=-16t^2+5t+15 to answer the

Fiesta28 [93]

Answer:

1) 1.1 seconds

2) 13.5 feet

$\rightarrow \sf -16t^2 + 5t + 15 = 0$

<u>Apply quadratic formula</u>:

$\rightarrow \sf t= \dfrac{-5\pm \sqrt{5^2-4\left(-16\right)\cdot \:15}}{2\left(-16\right)}$

<u>Simplify following</u>

$\rightarrow \sf t=-\dfrac{-5+\sqrt{985}}{32},\:t=\dfrac{5+\sqrt{985}}{32}$

In decimal form:

$\rightarrow \sf t=-0.825 ,\:t=1.137$

Conclusion:

As time is be only positive: t = 1.1 seconds

$\rightarrow \sf h=-16t^2 + 5t + 15$

<u>insert t = 0.5</u>

$\rightarrow \sf h=-16(0.5)^2 + 5(0.5) + 15$

<u>simplify</u>

$\rightarrow \sf h=13.5$
