Answer 2

Answer:

given;-

find the pathlength when body covers semicircular path or radius 100m?​

to find ;-

• Distance is the total amount of meters traveled.

• Displacement is the net change in meters.

solution;-

The particle (body) travels along the perimeter of a half-circle with radius  r=100 . The circle’s whole perimeter is  p=20πr .

The direct path from A to B is the diameter  20r=200  meters. This is the net displacement.

The full distance traveled is half the perimeter of the circle. The distance,  d=p20=πr=100π .
