A students walks one hour. She walks 4 blocks east and 2 blocks west. Her average velocity is?

The average velocity of the student is 2 blocks per hour.

The given parameters:

To find:

Let the eastward direction = positive direction

let the westward direction = negative direction

The average velocity of the student is calculated as the change in her displacement per unit time of the motion.

Thus, the average velocity of the student is 2 blocks per hour.

Let us consider the following figure

figure is in picture

So, his/her total displacement = 2 blocks.

total time = 1 hour

Average Velocity

= Total displacement/ total time

= 2 blocks/ 1 hour

= 2 blocks/ h

So, her/his average velocity is 2 blocks per hour.

it is the second option.

f=ma newton

f=100x2.5=250n
