Question

a cyclist follows a circular path, starting from a point A and he reaches back to A in 15s. What is his displacement?(radius=5m)​

Answer 1

Answer:

just zero

Explanation:

because unlike distance travelled displacement is final position subtracted by initial position;

so initially cyclist is at point A and even finally at A

just A-A=0

Answer 2

A cyclist covers a distance X in 15 sec..through a circular path...

given: radius= 5m

ans: displacement means in circular path i.e the circumference of the circle..

circumference of the circle= 2πr

=2*3.14*5

displacement =31.40m
