Question

A particle complete two and a half rotation around the circumference of radius 3 m find the distance travelled & the displacement of the particle​

Answer 1

Explanation:

convert 3m into com that is 300 cm

then permiter of circle is (pie r^2)

Answer 2

Answer

total distance :47.13m

displacement:6m

Explanation:

distance for 1 round =2*22/7*3=18.85m

distance for 2 round=18.85*2=37.71m

for half round = pie*r=22/7*3=9.42m

therefor total distance covered=37.71+9.42=47.13m

displacement for two rounds will be zero and for half round, it will be the diameter that is radius*2=3*2=6m
