Question

A body travels in a semicircular path of radius 10 m starting its motion from point ‘A’ to point ‘B’. Calculate the distance and displacement.

Answer 1

Total distance travelled by body, S = ?

π = 3.14, R = 10 m 

S = πR

= 3.14 × 10 m 

= 31.4 m Ans. 

Total displacement of body, D = ? 

Given, 

R = 10 m 

D = 2 × R 

= 2 × 10 m 

= 20 m
