1.	A car move from 30km/h and back with 60km/h.find average speed and velocity during the motion
Answer» 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 Hope this answer helped you

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

Answer»

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

Hope this answer helped you
