ok you divide 16÷2 then divide 75÷2 then you add the two anwers and you get it

Answer 2

Distance fell by rock in 2 seconds = 64 feet

Explanation:

An object falls 16t² feet in t seconds.

Now we are dropping an object from 75 feet above the water.

We need to find how much distance it falls in 2 seconds.

We have

Distance = 16t²

Distance = 16 x 2² = 64 m

So the rock will fall 64 feet in 2 seconds.

Distance fell by rock in 2 seconds = 64 feet
