Question

An object moves in a circular path of radius 35 metres in 10 minutes. Find out the distance travelled displacement and speed

Answer 1

Given, radius = 35 m
           circumference = 2 π r
                                   = 2 × 22 / 7 × 35
                                   = 44 × 5
                                   = 220 m
Time taken = 10 minutes
                   = 10 × 60
                   = 600 s
(i) Distance travelled = Circumference of the circular path
                                  = 220 m
(ii) Displacement travelled = 0 (∵ initial and final point are the same )
(iii) Speed = Distance travelled / Time taken
                 = 220 m / 600 s           (or)            = 220 m / 10 min
                 = 0.36.. m/s                                   = 22 m / min

Hope my answer helps you : )
