Question

a body moves from A to B along a semicircular path of radius R what is the distance tranversed and the displacement of the body​

Answer 1

Answer:

distance travelled is πr

and displacement travelled is 2r

Answer 2

Answer:

the distance travelled by a body from a to b is actual path travelled by a body as body cover semicircle so distance covered is =1/2 * perimeter of a circle 1/2*2πr = πr distance covered while displacement should be the least distance travelled by a body if we connect initial position to final position we get displacement and it is found be equal to 2 time of circular radius
