Question

• 1) If an object, moving along a circular path of radius "r", takes time "t" to come back to its starting position, its speed can be determined using the formula



Answer Should Be Correct Only ​

Answer 1

Explanation:

s = d/t

here the distance is 2πr as it is the circumference

and time is t

so speed = 2πr/t

Answer 2

Answer:

2πr/t

Explanation:

distance of circular path= circumference of circle=2πr

time taken =t

speed=distance/time

=2πr/t
