Question

I need to create a graph based off this paper

Answer 1

Answers:

2. Total Distance = 750 m

Total Time = 8 min

Average speed = 93.75 m/min

3. 200 m/min to the east.

4. Acceleration

Step-by-step explanation:

1.

Taking into account the description, we can graph the situation as follows:

2. Now, we can find the total distance and the total time traveled as follows:

Distance = 200 m + 100 m + 150 m + 200 m + 100 m

Distance = 750 m

Time = 3 min + 1 min + 1 min + 1 min + 1 min + (30 s + 30 s)

Time = 3 min + 1 min + 1 min + 1 min + 1 min + 1 min

Time = 8 min

Then, the average speed will be equal to:

Average Speed = Total Distance / Total time

Average speed = 750 m/ 8 min

Average speed = 93.75 m/min

3. The speed is calculated using the total distance traveled and the velocity is calculated using the displacement. It means that the velocity takes into account the direction of the movement, so the important points are only the initial and final position, to calculate the velocity, the path between the initial and final position doesn't matter.

Then, from point D to point E, we will find the velocity as follows:

`\text{Velocity}=\frac{200\text{ m East - 0 m}}{1\text{ min}}=\frac{200\text{ m East}}{1\text{ min}}=200\text{ m/min East}`

So, the velocity from point D to E is 200 m/min to the east.

4. There is acceleration when there is a change in the velocity. Since from point E to F, you start with a specific velocity and then change the velocity (start to run), we can say that the motion is best described as acceleration.
