Question

if an object covers a diatance of 20m in 10s and30m distance in 20 s and returned back to the same position calculate average speed and average velocity of an object .​

Answer 1

Avg. Velocity will be 0 as displacement travaalad is 0

Avg.Speed will be Total distance÷Total time = 50÷30 = 5÷3 = 1.6666666667m/s

Answer 2

Average speed = total distance/ total time = 20 + 30 / 10 + 20 = 50/30 = 1.66 m/s

Now since the body returned to where it started from

So,

Velocity = Displacement/ time = 0 / 20 = 0 m/s
