Selena is standing on a rock cliff that is 52 feet high. She tosses a pebble upward over the edge, where it hits the top of a 12

Ronch [10]

Answer: At $t=\dfrac{3}{8}$ , the pebble hit the top of the boulder.

Step-by-step explanation:

Since we have given that

Distance at which Selena is standing on a rock cliff = 52 feet

Height of boulder above a rock cliff = 12 foot

So, the given quadratic equation would be

$p(t)=-16t^2+12t+52$

First we derivative it w.r.t t,

$p'(t)=-32t+12$

Now, we will find the critical value,

$-32t+12=0\\\\-32t=-12\\\\t=\dfrac{12}{32}=\dfrac{6}{16}=\dfrac{3}{8}$

Now, we will check whether it is maximum or not.

$p''(t)=-32$

So, we get that it is maximum.

Hence, at $t=\dfrac{3}{8}$ , the pebble hit the top of the boulder.
