3. derek throws a baseball upward from an initial height of 3 ft. the baseball hits the ground after 2 seconds.
a. what was the initial velocity of the baseball?
b. what is the function that models the height, ℎ (in feet), of the baseball over a period of time tt (in seconds)?
c. at what time did the baseball reach its maximum height? what was the maximum height of the baseball?

Answer with Step-by-step explanation:

Since we have given that

Initial height = 3 feet

The baseball hits the ground after 2 seconds

t = 2 seconds

So, final velocity = v = 0

a. What was the initial velocity of the baseball?

Initial velocity is given by

b. What is the function that models the height, ℎ (in feet), of the baseball over a period of time tt (in seconds)?

As we know that the function of height would be

Here, is the initial height.

So, our function becomes,

c. At what time did the baseball reach its maximum height? What was the maximum height of the baseball?

Maximum height at time t:

Maximum height would be

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
