A body moves in uniform motion on a circular track with radius is 40 metre if he completes a cycle in 40 seconds what is the distance and displacement after 30 seconds

Answer 1

Explanation:

Displacement is the shortest distance travelled from the initial point to the final point. After half revolution the displacement is the length of the diameter which is equal to 2r. Hence the displacement is 2r.

Answer 2
