Question

A body completes one round of
a circle of radius is 'r'
20 Seconds . The ratio of displacement to distance after 10 seconds​

Answer 1

Assuming uniform motion, after 45 seconds body will have finished

20

45

=2.25 rounds, i.e., if it starts from A it will be at B after 45 seconds.

Now, displacement AB=

R

2

+R
