Question

A Particlle is moving in a circle of diameter
5 m. what is it is displacement when a
complete one and half revolution?​

Answer 1

Answer:

the answer is 2.5 m when he go on the half revolution

Answer 2

diameter = 5m

revolutions made = 1 and 1/2

Distance and displacement in one revolution:-

distance :- 2πr

displacement :- 0

distance and displacement in 1/2 revolutions:-

distance:-πr

displacement:-2r

Adding distance and displacement:-

distance:- 2πr+πr = 3πr

displacement:- 0+2r = 2r
