The function f(x)=5 square root of x gives the speed in feet per second (ft/s) of a freefalling 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.
