A man jogs at a velocity of 2.5 m/s west for 1,200 s. He then walks at a velocity of 1.0 m/s east for 500 s and then stops to re

Vinvika [58]

Answer:

The displacement is <u>2500 m</u> towards west.

Step-by-step explanation:

Taking west as negative direction and east as positive direction.

Velocity of man jogging west = -2.5 m/s

Time he traveled towards west = 1,200 s

Displacement in west direction = $Velcoty \times time=-2.5\ m/s\times 1200\ s=-3000\ m$

Velocity of man jogging east = 1.0 m/s

Time he traveled towards east = 500 s

Displacement in west direction = $Velcoty \times time=1.0\ m/s\times 500\ s=500\ m$

Total displacement can be calculated by finding the sum of displacement.

Total displacement = $-3000\ m+500\ m=-2500\ m$

Since, the resultant displacement is negative, so the displacement is 2500 m towards west.

What is the mean absolute deviation of the following data set

tatuchka [14]

Answer:

4.32

Step-by-step explanation:

First, we have to find the mean of the data set.

16, 11, 9, 12, 11, 10, 10, 8, 15, 0, 2, 15, 14, 7, 11, 5, 14, 20, 3, 11, 13, 7, 0, 5, 21 all added together equals 250. 250 divided by 25 = 10. So 10 is the mean.

Now we have to find the absolute distances of each number from the mean.

16 - 10 = 6... 11 - 10 = 1... so on, giving us this -->

6, 1, 1, 2, 1, 0, 0, 2, 5, 10, 8, 5, 4, 3, 1, 5, 4, 10, 7, 1, 3, 3, 10, 5, 11

Finally, we have to find the mean of the distances (which is done by adding all the numbers above and dividing the sum by the number of values there are).

108 divided by 25 = 4.32.

So, 4.32 is the mean absolute deviation (MAD) of the following data set.
