Question

a car move from 30km/h and back with 60km/h.find average speed and velocity during the motion​

Answer 1

Answer:

Average speed : 40km/hr

Average velocity : 0

Explanation:

Average speed= total distance covered /total time

Let the distance from start to end point be L km

Total time=(L/30)+(L/60)=L/20

Average speed = 2L/(L/20)=40

Average velocity is zero because DISPLACEMENT is zero
