Question

consider an odject travelling in a semi circular path from point O to point P in 5 second, as shown in the Figure given below . Calculate the average velocity and average speed.​

Answer 1

Explanation:

1) Average velocity = Total Displacement

Total time

Here , Total displacement is equal to "10cm"

because it is the shortest distance

and , Total time is "5 sec"

by putting this values in formula you will get

2cm/s

2) Average Speed = Total distance travelled

Total time taken

Total distance for a circle =2πr

but here , distance will be 2πr/2

and time will be 5 sec

by putting this values in formula you will get

πr /5 = 2π

Answer 2

Answer:

average velocity=v1+v2/2

therefore use this formula as an answer in given values....
