Question

a body travels from A to B at 40 m/s and from B to A at 60 m/s. calculate the average speed and average velocity.​

Answer 1

Answer:

50

Explanation:

average velocity=

average speed=60+40/2

=100/2

=50

Answer 2

Answer:

d is the distance between a and b, total distance travelled is 2d. Total time taken is (d/40) + (d/60). Hence average speed = total distance/total time taken = 48 m/s.

Average velocity = displacement/time. Since the body is back to same point, displacement = 0. Hence ave. velo. = 0.
