Answer:

The answer is Average speed is equal to 12.5 m/sec

Explanation:

1- The average speed is the relationship between the distance traveled that a body made and the total time it took to perform it.

2- The formula that allows to calculate the average velocity is V = ΔX/ΔT where (V) is the average speed, (ΔX) is the distance traveled and (ΔT) is the time interval.

3- Knowing this we can replace the values given in the problem:

V = \frac{400m}{32sec} \\V = 12.5  m/sec

To find average speed, we divide the distance of travel (in this case, 400 metres) by the time she took, 32 seconds.  Therefore: 12.5 seconds is her average speed.

a college student rests a backpack upon his shoulder. the pack is suspended motionless by one strap from one shoulder.
Minchanka [31]

The student's shoulder supports the weight of the bag.

<h3>What is the free body diagram?</h3>

Free-body diagrams are utilized to display the relative direction and strength of all forces that are being applied to an item in a certain scenario. A unique illustration of the geometric diagrams that were covered in a previous lesson is the free-body diagram. We will make use of these graphics throughout the entire study of physics.

A university student is carrying a backpack. One strap is hanging the rucksack immobile from one shoulder.

The weight of the backpack is balanced by the shoulder of the student.

The free-body diagram is attached below.

More about the free body diagram link is given below.

A race car accelerates uniformly at 14.2 m/s2. If the race car starts from rest how fast will it
Kaylis [27]

Answer:

vf=94.4 m/s

Explanation:

acceleration is the final velocity minus initial velocity divided by time

a = (vf-vi)/t

Given:

a= 14.2 m/s^2

vi= 0 (at rest)

t = 6.6

Solve for vf

a = (vf-vi)/t

a*t=vf-vi

(14.2)*(6.6)=vf - 0

vf=94.4 m/s
