Answer: 8.73 ft/s
Step-by-step explanation:
We have the following equation that models the motion of the rock:
Where is the height of the rock at a time
.
Now, if we can find
and then the velocity of the rock at that height:
Rearranging the equation:
Multiplying the equation by -1:
Solving with the quadratic formula , where
,
,
.
Choosing the positive result of the equation:
Since velocity is defined as the traveled distance
in a given time
, we have:
This is the velocity of the rock at the height of 48 feet
