3. Derek throws a baseball upward from an initial height of 3 ft. The baseball hits the ground after 2 seconds.
mariarad [96]

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

v_0=\dfrac{3}{2}=1.5\ ft/sec

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

h(t)=-16t^2+v_0t+h_0

Here, h_0 is the initial height.

So, our function becomes,

h(t)=-16t^2+1.5t+3

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

Maximum height at time t:

t=\dfrac{-b}{2a}=\dfrac{-1.5}{2\times -16}=\dfrac{1.5}{32}\approx 0.05\ seconds

Maximum height would be

h(0.05)=-16(0.05)^2+1.5\times 0.05+3=3.035\ ft

The sum of 13 and twice a number is seven less than six times a number. what is the number
Trava [24]
Let, the number = x
It would be: 13 + 2x + 7 = 6x
2x+20 = 6x
6x-2x = 20
4x = 20
x = 20/4
x = 5

In short, Your Answer would be 5

Hope this helps!
