Question

an object moves around a circular track of radius 10 m with speed pie m/s. find the displacement in 10 s​

Answer 1

Answer:

20m

Explanation:

Radius = r = 10m, speed = π m/s, time = 10 seconds

distance covered in 10 seconds = 10π

circumference = 2*π*10 = 20π m

therefore only of the circular track is covered.

Hence, net displacement = diameter = 2r = 20m.

Hope it helped.
