(1) When Emma is standing at the top of the mountain, the energy encountered is potential energy.

(2) When Emma is jumping down from the mountain top, the energy encountered is both kinetic energy and potential energy.

(3) The energy creating the tensional force on the rope at Emma’s lowest position is elastic potential energy.

(4) When Emmas is bouncing back, he will encounter both kinetic energy and potential energy.

<h3>Conservation of energy</h3>

The energy encountered by Emma and the rope at each point is determined from the principle of conservation of mechanical energy.

<h3>1.0 Emma standing on top of mountain </h3>

When Emma is standing at the top of the mountain, the energy encountered is potential energy this is due to his position above the ground level.

P.E  = mgh

<h3>2.0 Emma jumping down from mountain top</h3>

When Emma is jumping down from the mountain top, the energy encountered is both kinetic energy and potential energy. This is as a result of his position above the ground level and his motion downwards.

M.A = K.E + P.E

<h3>3.0 Tension in rope at Emma’s lowest position</h3>

The energy creating the tensional force on the rope at Emma’s lowest position is elastic potential energy.

U = ¹/₂kx²

<h3> 4.0 Emma bouncing back</h3>

When Emmas is bouncing back, he will encounter both kinetic energy and potential energy due to his motion and position above the ground.

Find the sum.
Strike441 [17]

You are gonna use the distributive property.

4(2.5g - 4) + 3(1.2g - 2)

So you are going to multiply 4 with everything inside the first set of parenthesis and your gonna multiply 3 with everything insides the second set of parenthesis.

4 x 2.5g - 4 x 4 + 3 x 1.2g - 3 x 2

10g - 16 + 3.6g - 6

You wanna combine like terms:

10 - 3.6g + 16 - 6

6.4g + 10

You answer is 6.4g + 10.

Hope this Helps!!

A local orange grower processes 2,330 oranges from his grove this year. The oranges are packaged in crates that each holds 96 or
maw [93]

Answer:

13

Step-by-step explanation:

Given parameters:

Number of oranges processed by grower  = 2330 oranges

Number of oranges per crate  = 96

Unknown:

Number unpacked oranges

Solution:

To solve this problem, divide the total number of oranges by the number of oranges per crate;

  Number of unpacked oranges  = \frac{2330}{96}  

  Number of unpacked oranges  = 24 \frac{13}{48}  

The remaining unpacked is 13.

A circle with radius 9 has a sector with a central angle of 120°.
Vitek1552 [10]

120º is 1/3 of a complete revolution of 360º. So the area of this sector should be 1/3 the area of the complete circle.

A circle with radius 9 has area 9^2 π = 81π.

So the sector has area 81π/3.

Put another way: The area <em>A</em> of a circular sector and its central angle <em>θ</em> (in degrees) occur in the same ratio as the area of the entire circle with radius <em>r</em> according to

<em>A</em> / <em>θ </em>º = (π <em>r </em>^2) / 360º

==>  <em>A</em> = π/360 <em>θ r</em> ^2

In this case, <em>r</em> = 9 and <em>θ</em> = 120º, so

<em>A</em> = π/360 * 120 * 81 = 81π/3
