Q

# Joseph jogs from one end A to the other end B of a straight 300 m road in 2 minutes 30 seconds and then turns around and jogs 100 m back to point C in another 1 minute. What are Joseph’s average speeds and velocities in jogging (a) from A to B and (b)

Joseph jogs from one end A to the other end B of a straight 300 m road in 2 minutes 30 seconds and then turns around and jogs 100 m back to point C in another 1 minute. What are Joseph’s average speeds and velocities in jogging

(a) from A to B and

(b) from A to C?

Views

Given,

(a) Distance between A and B =

Time taken to reach from A to B =

Average speed from A to B =

And, Average velocity from A to B =

(In this case, average speed is equal to the average velocity)

(b) Distance travelled from A to reach C =

And, Displacement from A to C =

Also, time taken to reach C from A =

Average speed from A to C =

And, Average velocity from A to C =

(In this case, average speed is not equal to the average velocity)
