Question

a object moves in a path with radius r find the distance covered and dispalcement when it will complete half a revolution

Answer 1

Answer:

Since radius is given it moves in a circular path

distance(half revolution)= 1/2 × 2πr

                                       = πr

displacement = 2r                       [ ∵ shortest distance is calculated, in a

                       = d                           semi-circle the diameter will be the                          

                                                       shortest distance.]
