Question

1. A road roller travels 50 m distance on straight path in 10 seconds. It covers next 25 meters in opposite direction in 5 seconds. Find Average speed and Average velocity for it.​

Answer 1

Answer:

Explanation:

Average speed = Total distance covered / total time

                          = (50 + 25)/(10 + 5)

                          = 75/15

                          = 5 m/s

Average velocity = Displacement/Time

                            = (50-25)/15

                            = 25/15

                            = 1.67 m/s
