The formula v =sqrt 64h can be used to find the velocity, v, in feet per second, of an object that has fallen h feet. find the velocity of an object that has fallen 23 feet. round to the nearest tenth.,

To solve the problem shown in the figure attached in the exercise, you must follow the proccedure shown below:

 1. You have that the formula for calculate the velocity (v) in feet per second (ft/s), of an object that has fallen h feet is:

 v=√(64h)

 2. The problem shown above asks for the velocity of an object that has fallen 23 feet. Therefore, to solve this exercise you only have to susbtitute h=23 feet into the formula for calculate the velocity (v), as below:

 v=√(64h)

 h=23 feet

 v=√(64)(23)
 v=√(1472)
 v=8√23
 v=38.37 feet per second

 3. Therefore, as you can see, the correct answer is the second option, which is: 38.37 feet per second
