The function f(x)=5 square root of x gives the speed in feet per second (ft/s) of a free-falling object after it has fallen x feet (ignoring air resistance). FInd the speed of the object after it has fallen 25 feet. If necessary, round your answer to the nearest tenth.
Not sure if there is a typo in your question, the speed is
y(x)=5√(x)=5√(25)=25
This corresponding an equivalent acceleration approximately that of Mars.
To find the speed of the object after it has fallen 25 feet, we can substitute x = 25 into the function f(x) = 5√x, where f(x) represents the speed in ft/s.
Replacing x with 25, we have:
f(25) = 5√25
To evaluate the square root of 25, we know that √25 = 5, since 5 * 5 = 25.
So, f(25) = 5 * 5 = 25 ft/s.
Therefore, the speed of the object after it has fallen 25 feet is 25 ft/s.
