A boy travelled in a circular path and reached to the initial position 'O'. If the radius of the circle is 7 m. Find the distance covered and the displacement of the body.

Text Solution

Verified by Experts

Since the initial and final position of the body is coinciding, the length of the straight line drawn from the initial position to the final position is zero. Therefore, displacement is zero. Radius = 7 m
Distance travelled = Circumference of circle = `2pir`
`= 2 xx(22)/(7)xx7 = 44m therefore vec(s) = 0` and S = 44 m
