Question

While loading, a truck moves 10 meters west from point A to point B in 5 seconds Then it moves back to point A in 5 seconds What are the average speed and average velocity of the truck

Answer 1

average speed = 2 meters/second

average velocity = 0 meters/second

Explanation:

1) The total distance traveled is 20 meters.

2) The total displacement is 0 meters.

3) Substitute these values in the formula for speed and velocity

4) You get an average speed of 2 meters per second and an average velocity of 0 meters per second.

Answer 2

Average speed = (distance covered) / (time to cover the distance)

Average speed = (10m + 10m) / (5sec + 5sec)

Average speed = 20m / 10sec

Average speed = 2 m/s
____________________________________________

Average velocity = displacement/time

Displacement = (distance and direction from start-point to end-point) .

The truck started at point-A and ended at point-A .

Displacement = 0 .

Average velocity = ( 0 ) / (10 sec)

Average velocity = 0
