Question

body in is moving in a circular track of diameter 100 M in 40 seconds what will be the distance and displacement in 42nd 2014 and 22nd​

Answer 1

Distance = 100m; t = 40s

I believe that you wanted to say 42 s & 22 s, if not, pls correct your question.

Also, don't write metres in M instead of m.

Distance covered in 40s = 100m

Distance covered in 1s = 100 / 40 = 2.5m

Distance covered in 42s = 2.5 x 42 = 105m : Ans

Distance covered in 22s = 2.5 x 22 = 55m : Ans

Displacement in both cases = 0 : Ans (displacement is always 0 in a circular motion)

Hope I helped
