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

Text Solution

Verified by Experts

The distance covered by the person equals the length of the track. It is equal to `piR = pi xx40.0m=126m`.
The displcement is equal to the diameter of the semi circular track joining the two ends. Ilt is `2R=2xx40.0m=80m`. The direction of this displacement is from the initial point to the final point.
