Question

a man move half revolution among the circular path of radius r . write the distance travelled by him and his displacement.​

Answer 1

Answer:

distance=πr

displacement =2r=d

Answer 2

Half revolution means he has travelled along a semicircle of radius r.

Distance = 2 × 3.14 × r = 6.28r

Displacement (shortest distance between initial and final point)

= 2r
