Answer 1 · 2017-12-25T07:05:27

THe answer is $= 187.5 m$ $=187.5m$

Explanation:

The height is given by the equation

$h (t) = 300 + 2 t - 4.9 t^{2}$ $h(t)=300+2t-4.9t^2$

When $t = 5 s$ $t=5s$ , we have

$h (5) = 300 + (2 \cdot 5) - 4.9 \cdot (5^{2})$ $h(5)=300+(2*5)-4.9*(5^2)$

$= 300 + 10 - 122.5$ $=300+10-122.5$

$= 187.5 m$ $=187.5m$

See below.

Explanation:

If at first you don't understand what a word problem is asking for, read, read again!

In order to solve this problem, we are given that the time ( $t$ $t$ ) is $5$ $5$ seconds. We are asked to find the corresponding height, $h$ $h$ value.

So what you need to do is substitute $5$ $5$ for $t$ $t$ in the above equation and solve for $h$ $h$ . I will leave this to you, as it shouldn't be too challenging.*

I hope that helps!
