Kevin Fast pulled a CC- 177 Globemaster airplane 8.8m. he plane weighed 188 tons. How many pounds did the lane weigh?
DedPeter [7]

Answer:

376000 pounds

Step-by-step explanation:

What's required of this question is to convert the given weight of plane from tons to pounds

Given

Weight = 188\ tons

Required

Get pounds equivalent

From standard unit of measurements

1\ ton = 2000\ pounds

Multiply both sides by 188

188 * 1\ ton = 188 * 2000\ pounds

188\ tons = 376000\ pounds

<em>Hence, the weight of the plane in pounds is 376000</em>

The diameter of the earth
Roman55 [17]

Answer:

25,132.74 miles

Step-by-step explanation:

Hello!

We are basically asked to find the circumference of the Earth's cross-section.

Circumference: C = 2\pi r

We can replace 2r with the diameter, because the diameter is 2 times the radius.

Multiply the Diameter by pi:

  • C = \pi D
  • C = 8000\pi
  • C = 25,132.7412287183  \approx 25,132.74

It is around 25,132.74 miles around.

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
