Answer:
69.74 feet per second is the velocity of an object that has fallen 76 feet
Step-by-step explanation:
As per the statement:
The formula v = square root of 64h gives the velocity v in feet per second of an object that has fallen h feet.
⇒[tex]v = \sqrt{64h}[/tex]
where, v is the velocity in feet per second and an object that has fallen h feet.
We have to find the velocity of an object that has fallen 76 feet.
⇒ h = 76 feet.
Substitute in the given formula we have;
[tex]v = \sqrt{64 \cdot 76} = \sqrt{4864} = 69.7423831[/tex] feet per second
Therefore, the velocity of an object that has fallen 76 feet to the nearest hundredth is, 69.74 feet per second
