Question

plz!!!!! answer with explaination!!!!!!

Answer 1

Hey mate,
Here is your answer-
Zero....
Because whenever a body travels in circular path and after some time it will back on same point then there is no displacement....

Answer 2

given

r=40m

circumference=2*π*40=80π

t=40s

s=80π/40=2π

so

d=s*t

d=2π*220

d=440π

no of revolution=440π/2π
so no of revolution=220
there for partical will be in same point
so displacement is 0
