Question

a man running on a circular track of radius 35 metre complete 4 rounds what is the distance and displacement???​

Answer 1

Explanation:

In one complete cycle, it comes back to its initial position, so the displacement of the object is zero.

Distance travelled = circumference of the circle = 2πr

=2×

7

22

×3.5

=22m

Answer 2

Answer:

A MAN RUNNING ON A CIRCULAR TRACK OF RADIYS 35 M. AND COMPLETED 4 ROUNDS.

DISTANCE COVERED = CIRCUMFERENCE OF CIRCLE:

$2\pi \: r$

AS THE MAN COMPLETE 4 ROUNDS:

$4 \times 2\pi \: r \\ \\ = 4 \times \frac{22}{7} \times 35 = 440m$

NOW DISPLACEMENT IS 0M . AS HE COMPLETED 4 ROUNDS COMPLETED.
