Explanation:

The graph below shows the position of an ant as it crawls over a flat picnic blanket. The total time for the ant to go from the start to the end position takes 1 minute and 45 seconds.


What is the average speed and average velocity of the ant?

A.) Average speed is 0.200 cm/s and average velocity is 0.0988 cm/s to the upper right.
B.) Average speed is 0.152 cm/s and average velocity is 0.910 cm/s to the upper right.
C.) Average speed is 0.975 cm/s and average velocity is 1.95 cm/s to the upper right.
D.) Average speed is 0.276 cm/s and average velocity is 0.136 cm/s to the upper right.

Answers

The average speed of the ant is 0.276 cm/s and the average velocity is 0.136 cm/s.

The correct answer is option D.

In the given graph, we can deduce the following;

the total time of the motion, = 1 mins + 45 s = 60 s + 45 s = 105 s

The average speed of the ant is calculated as;

[tex]average \ speed = \frac{total \ distance }{total \ time }[/tex]

The total distance from the graph is calculated as follows;

first horizontal distance from 2 cm to 8 cm = 8 - 2 = 6 cmfirst upward distance from 3 cm to 5 cm = 5 - 3 = 2 cmsecond horizontal distance from 8 cm to 6 cm = 8 - 6 = 2 cmsecond upward distance from 5 cm to 12 cm = 12 - 5 = 7 cmthird horizontal distance from 6 cm to 13 cm = 13 - 6 = 7 cmfourth downward distance from 12 cm to 9 cm = 3 cmfinal horizontal distance from 13 cm to 15 cm = 2cm

The total distance = (6 + 2 + 2 + 7 + 7 + 3 + 2) cm = 29 cm

[tex]average \ speed = \frac{total \ distance }{total \ time } = \frac{29 \ cm}{105 \ s} = 0.276 \ cm/s[/tex]

The average velocity is calculated as the change in displacement per change in time.

The displacement is the shortest distance between the start and end positions.

This shortest distance is the straight line connecting the start and end position. Call this line PFrom the end position at x = 15 cm, draw a vertical line from y = 9 cm, to y = 3 cm. The displacement = 9 cm - 3 cm = 6 cmAlso, draw a horizontal line from start at x = 2 cm to x = 15 cm. The displacement = 15 cm - 2 cm = 13 cm

Notice, you have a right triangle, now calculate the length of  line P.

                                                ↓end

                                                ↓

                                                ↓ 6cm

                                                ↓

  start -------------13 cm------------

Use Pythagoras theorem to solve for P.

[tex]P^2 = 6^2 + 13^2\\\\P^2 = 36 + 169\\\\P^2 = 205\\\\P= \sqrt{205} \\\\P = 14.318 \ cm[/tex]

The average velocity of the ant is calculated as;

[tex]average \ velocity= \frac{\Delta displacemnt }{total\ time }= \frac{14.318 \ cm}{105 \ s} = 0.136 \ cm/s \\\\[/tex]

Thus, the average speed of the ant is 0.276 cm/s and the average velocity is 0.136 cm/s.

Which of the following best represents R=A+B ?
A)

B)

C)

Answers

Answer:

C

Explanation:

Options A and B are not even pointing in the direction as the vectors in the question so they shouldn't even be considered.

Option C looks like the closes since vectors A and B are pointing in a similar direction (negative x-axis)

The best representation for the resultant vector representing the resultant R=A+B would be option C because the result is represented by the closing side of the triangle, therefore the correct answer would be C.

What is a vector quantity?

The quantities that contain the magnitude of the quantities along with the direction are known as the vector quantities.

Examples of vector quantities are displacement, velocity acceleration, force, etc.

As given in the problem we have to find out the resultant vector from the sum of vector A and vector B,

The resultant of the vector can be calculated with the help of the triangle law of the vector addition in which the sum is given by the closing side of the triangle.

Thus, the correct answer is option C.

The distance from Atlanta to Macon is about 80 miles out of 58.5° south of east. What distance is dues east and dues south mustyou drive in order to travel from Atlanta to Macon?

Answers

Answer:

One must drive [tex]$41 \cdot 8\,miles$[/tex] north and [tex]$68 \cdot 24\,miles$[/tex] south, in order to travel from Atlanta to Macon.

Explanation:

• The distance of an object can be defined as the complete path travelled by an object.

• To find the distance, find its north component.

• For reference see the below graph:

[tex]$$\[\begin{align}& D_{south} = 80\sin \left( {58 \cdot {5^ \circ }} \right) \\& D_{north} = 80\cos \left( {58 \cdot {5^ \circ }} \right) \\\end{align}\]$$Since, $\sin \left( {58 \cdot {5^ \circ }} \right) = \cdot 853$ and $\cos \left( {58 \cdot {5^ \circ }} \right) = \cdot 5224$: therefore,$$\[\begin{align} D_{south} &= 80 \times \left( { \cdot {{853}^ \circ }} \right) \\ \Rightarrow {D_{south}} &= 68 \cdot 24\,miles \\ \end{align}\]$$[/tex]

And

[tex]$$\[\begin{align} D_{north}& = 80 \times \cdot 5224 \\ \Rightarrow D_{north}& = 41 \cdot 8\,miles \\ \end{align}\]$$[/tex]

• Hence, one must drive [tex]$41 \cdot 8\,miles$[/tex] north and [tex]$68 \cdot 24\,miles$[/tex] south, in order to travel from Atlanta to Macon.

what is work - energy theorem ??​

Answers

The work-energy theorem explains the idea that the net work - the total work done by all the forces combined - done on an object is equal to the change in the kinetic energy of the object. After the net force is removed (no more work is being done) the object's total energy is altered as a result of the work that was done.

This idea is expressed in the following equation:

is the total work done

is the change in kinetic energy

is the final kinetic energy

a car is traveling north. can its acceleration vector ever Point South? explain​

Answers

Yes.

The acceleration vector WILL point south when the car is slowing down while traveling north

When a car is traveling north, its acceleration vector can point south when it is slowing down.

A vector quantity has both magnitude and direction. The direction of a vector is always shown by the direction to which the arrow points.

If the car is travelling north, the direction of the acceleration vector will continue to point northwards.

However, when the car slows down, the direction of the accelerating vector will now point southwards.
