Sharon is jumping from an 18-foot diving board with an initial upward velocity of 4 ft/sWhen Sharon jumps, Megan throws a beach
likoan [24]

Answer:

1.08 seconds

Step-by-step explanation:

given data

<u>first equation:</u>

According to the data, sharon position will be

h(t)= -16 t^{2} + 4t +18---->eq(1)  

<u>Second equation;</u>

When Sharon jumps, Megan throws a beach ball up to Sharon with an initial upward velocity of 16 ft/s from a height 5 feet off the ground to the nearest hundredth of a second

therefore, ball position would be

h(t)= -16t^{2} +16t +5 --->eq(2)

In order to find how long after she jumps does the ball reach Sharon i.e time, we will equate eq(1) and eq(2)

Therefore,

eq(1)= eq(2)

-16t^{2} +4t +18 = -16t^{2} + 16t +5  --->(further simplifying it)

-16t^{2} + 16t^{2} + 18 -5 = 16t - 4t

13 = 12t

t= 13/12

t= 1.08 s

Thus it took 1.08 seconds.
