Given:
Radii of the circular path = 5 c.m.
To Find: Displacement after completing ½ the path.
...
Since displacement is the shortest distance between the initial and the final position, we can tell that diameter becomes the displacement.
So,
Displacement = Diameter of the path
= 2 × radius
= 2 × 5 c.m.
= 10 c.m.
∴ The displacement would be 10 c.m.s.
More: See attached figure.
Arc OB shows the distance and line segment OB shows the displacement. O is the initial position, A is the centre of the path and B is the final position of the particle.
