Question

A body requires 10 second to complete one rotation in a circular path with speed 13.2 m/s . The radius of the path is​

Answer 1

GIVEN,

time taken=10 s

speed=13.2 m/s

____________________

TO FIND,

• radius of the circular path

____________________

solution"

distance=speed *time

= 10*13.2

=132meter

hence, distance covered by the body on circular path is 132m that is circumference of the circle .

circumference of circle=2π r

=>132=2*22/7*r

=>132*7/44=r

or, r=28meter

hence , radius of circular path=28metre.
