Answer:

<em>1.0625 seconds</em>

Step-by-step explanation:

Given that:

Initial velocity of Belinda, v_0=17\ ft/sec

Height in feet of Belinda above the trampoline is given as the formula:

d(t) = v_0t-16t^2

Where t is the time in seconds.

To find:

Time taken by Belinda to come back to trampoline = ?

Solution:

When Belinda will come back to trampoline, the height will be zero.

Putting d(t) =0

We have the equation as:

0 = 17t-16t^2\\\Rightarrow 16t^2-17t=0\\\because t\neq0\\\Rightarrow 16t=17\\\Rightarrow t=\dfrac{17}{16}\\\Rightarrow t =1.0625\ seconds

Therefore, the answer is: <em>1.0625 seconds</em>
