A person moves on semicircular track of ...

A person moves on semicircular track of radius 40 m. If he starts from one end of the track and reaches at the other end. Find the distance covered and magnitude of displacement of the person.

Text Solution

Verified by Experts

Distance = path length = `(1)/(2) xx ` circumference
` = (1)/(2) xx 2 pi R = piR = (40 pi ) `m,
Displacement = `|vecd| = 2r = 80` m
