Question 894072
this should simply be a matter of replacing d with 8.5 and solving.


the formula is v = sqrt(32d).


d = 8.5 feet.


the formula becomes v = sqrt(32*8.5) which becomes:


v = sqrt(272) which is equal to 16.4924225 feet per second.


if you need an exact answer, then the exact answer is v = sqrt(272).


otherwise you can round to the number of decimal places you require.
