Question 291156: The formula t=square root of d over 16, describes the amount of time t,in seconds, that an object falls a distance of h feet.
a) write an expression in simplest form for the exact amount of time an object falls a distance of 64 feet.
b)Find the distance an object falls in 9 seconds.
Please help me I'm a 32 year old stay at home mom that has gone back to college

I'm assuming that the formula given to you is
a)
Start with the given equation.
Plug in
Divide 64 into 16 to get 4.
Take the square root of 4 to get 2.
So it takes 2 seconds for an object to fall 64 ft.
========================================================
b)
Start with the given equation.
Plug in
Square both sides to eliminate the square root.
Square 9 to get 81.
Multiply both sides by 16 to isolate 'd'
Multiply
So the answer is which means that the object has fallen 1,296 ft in 9 seconds.
