Find the hang time for a golf ball hit 150 feet into the air. The time T in seconds is given by the function

Question

T(x)= square root of x over 2

Answer 1

I assume x is the height in feet ?

is it T(x) = √x/2 or √(x/2) ??

if will assume the first,
t(150) = √150/2 = appr 6.12 seconds

If I assumed incorrectly, repeat my steps using the second equation.
