Question

a body is moving along a circular track of radius r. what is the distance and displacement of the body,when it completes two and a half revolutions?
1) distance 5πr and displacement 2πr
2) distance 2πr and displacement 5πr
3) distance 2r and displacement 2r
4) distance 5πr and displacement 2r
I need step by step easy explanation if possible please.​

Answer 1

Answer:

displacement is 24

explanation :

Displacement is the shortest distance travelled from the initial point to the final point. After half revolution the displacement is the length of the diameter which is equal to 2r. Hence the displacement is 2r.

Answer 2

Hey mate

Answer is 24
