Question

girl moving along a circular path of radius 14 m completes half the journey along the circle. Find:(a) distance covered by her and (b) displacement. If she covers full circle l,how the values of distance and displacement would modify?​

Answer 1

Answer:

For half journey A)44 B) 28

For full journey A)88 B)0

Explanation:

For half journey:

Displacement = 2r = 28m

Distance covered = 2πr/2 = 44m

For a full circle:

Displace ment = 0m [Same starting and ending point]

Distance covered = 2πr = 88m
