A particle moves along a semicircular path of radius R in time t with constant speed. For the particle calculate

A

distance travelled

B

displacement

C

average speed

D

average velocity

Text Solution

Verified by Experts

(i) Distance=length of path of particle=`hat(AB)=piR`
(ii) Displacement = minimum distance between initial and final point
=AB=2R
(iii) Average speed, v`=("total distance")/("time")=(piR)/(t)`j
(iv) Average velocity=`(2R)/t`
