An acorn falls from the branch of a tree to the ground 25 feet below. The distance, S, that the acorn is from the ground as it f

Hunter-Best [27]

Answer:

$0$

Step-by-step explanation:

We are given that,

The fall of the acorn is represented by the function,

$S(t) =-16t^2+25$

Equating S(t) to 0 gives,

$0=-16t^2+25$

i.e. $16^2=25$

i.e. $t^{2}=\frac{25}{16}$

i.e. $t=\pm \frac{5}{4}$

Since, time cannot be negative.

So, $t=\frac{5}{4}$ i.e. 1.25 seconds is the time when the acorn will reach the ground.

Thus, from the figure below, we see that,

The interval in which the acorn is in the moving air is $0$ .

ben drives from a 36- foot platform. The equation h= -16t^2+14t+36 models the dive. How long will it take Ben to reach the water

Valentin [98]

So you want to plug in the height for h and solve for t

36 = -16t^2+14t+36
So you get 14/16 which simplifies to
7/8 seconds

Hope this helped!
