Question

In one second a particle goes from a point a to another point b moving in a semi circle of radius one meter as shown in the figure.The average speed is​

Answer 1

Answer:

3.14m/s

Explanation:

Given radius, r=′1′m

Total distance =πr

                        =(3.14)(1)

                        =3.14m

Total time =1sec

Avg. speed =13.14

                    =3.14m/s
