Question

What is the distance and displacement if a body moves along a circular Path of radius 20m and after completing 2.5 revolution

Answer 1

Answer:

displacement=40 m

Distance=314.28

Explanation:

For 2.5 revolution r=20 m

Displacement=2r (because on completion of 1 revolution Displacement becomes zero)

=2×20=40 m

Distance covered in one revolution=2×22/7×r

=2×22/7×20=125.71 m

So distance in 2.5 revolution=125.71×2.5 m

=314.28

Answer 2

Answer:

The distance is 314m and the displacement is 40m.

Explanation:

Distance is the total path covered which is equal to 2.5*2*pi*radius.

Displacement is the shortest distance from the initial to the final position. So, it will be the diameter of the circular path which is equal to 40m.
