A baseball is thrown upward and out. It follows the equations: x = 9.8t
y = -16t^2 + 128t, where t is measured in feet/sec

a. how high is the ball after 1 second?
b. when does the ball hit the ground?
c. when is the ball at its highest point? what is the highest point of the ball?

No, the rock will not hit the water in 2 second but it will hit the water in t ≅ 2.17 second

Step-by-step explanation:

Let the distance be s in feet. i.e,   where t is in second.

You drop a rock from a bridge that is 75 feet above the water.

Use the  expression to solve for t:

Given: s =75 feet

then, substitute in the above expression:

or we can write it as:

or

⇒ t = 2.16506351 or t ≅2.17 second

Therefore, the rock hit the water in t≅2.17 second
