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

da freeck kinda math is this just drop out

step-by-step explanation:

they disappear if your absent from to long. i found out that the hard way.

step-by-step explanation:

brainliest lol i just need one more brainliest.
