The speed of a 2. 0-kg object changes from 30 m/s to 40 m/s during a 5. 0-s time interval. During this same time interval, the v

abruzzese [7]

The magnitude of the average total force acting on the object during this time interval is equal to 20 Newton.

<u>Given the following data:</u>

Mass = 2.0 kg

Initial velocity = 30 m/s

Final velocity = 40 m/s

Time = 5.0 seconds.

Angle = 90°

To calculate the magnitude of the average total force acting on the object during this time interval:

<h3>Newton's Second Law of Motion</h3>

In order to solve for the force acting on the dummy, we would apply Newton's Second Law of Motion.

<u>Note:</u> The acceleration of an object is equal to the rate of change in velocity with respect to time.

Mathematically, Newton's Second Law of Motion is given by this formula;

$F = \frac{M(v\;-\;u)}{t}$

Substituting the given parameters into the formula, we have;

$F_A = \frac{2(30\;-\;0)}{5}\\\\F_A = \frac{2\times 30}{5}\\\\F_A = \frac{60}{5}$

Force A = 12 Newton.

<u>For the second force:</u>

$F_B = \frac{2(40\;-\;0)}{5}\\\\F_B = \frac{2\times 40}{5}\\\\F_B = \frac{80}{5}$

Force B = 16 Newton.

Now, we can calculate the magnitude of the average total force acting on the object during this time interval:

$F = \sqrt{F_A^2 + F_B^2} \\\\F = \sqrt{12^2 + 16^2}\\\\F = \sqrt{144 + 256}\\\\F=\sqrt{400}$

Total force = 20 Newton.

A small office supply store sells paper clips in packs of 100 and packs of 250. If the store has 84 packs of paper clips in stoc

sveta [45]

Let x and y be the number of packs with 100 and 250 paper clips, respectively. The system of linear equations that would best represent the given is
x + y = 84
100x + 250y = 12,300

The values of x and y from the equations are 58 and 26, respectively. If a person buys half of the packs of 250 paper clips,
n = (0.5)(250)(26) = 3250

Thus, a person bought 3250 paper clips.

Determine where the "Sample Word" should be placed alphabetically in the list of words below. The word may belong at the beginni

fredd [130]

The “Sample Word” canyon, should be placed alphabetically in the list of words below after the Canvas at second place.

<h3>What is alphabetical order?</h3>

The alphabetical order is the system of arrangement of the words or latter in a way such that the conventional way of alphabet order.

For example in word "Apple" and "Ant", word ant comes first in alphabetical order as the second letter of the "Ant" word comes before than the second latter of first word "Apple".

The Sample Word, given in the problem, is,

$\text{canyon}$

The alphabetical order given as,

$\text{ canvas , capable ,cape ,capital}$

First and second word is same in all the latter, but third word of "Canyon" and "Canvas" comes earlier. The word "Canyon" should place at second position as the 4th latter 'y' of this latter comes after 4th latter of canvas.

Thus, the “Sample Word” canyon, should be placed alphabetically in the list of words below after the Canvas at second place.
