Question

a body travels from A to B at 40 metre per second A and B to a at 60 metre per second calculate the average speed of the object and velocity of object​

Answer 1

Average speed = 2V1V2 / V1 + V2

= 2 x 60 x 40/ 60+40

= 4800/100

= 48 m/s

Average velocity = Total displacement / Total time = 0 (Since the body returns to its initial position, Total displacement = 0)
