Question

8. A particle travelled along a semi circular path A-C-B as shown in the figure. The radius of the
semi circular path is 7m.
с
B
(a) Find the distance travelled by the particle.
(b) Find the displacement,
(c) What would be these quantities if the particle completes the circle?​

Answer 1

Explanation:

a. distance traveled by particle is perimeter of semi circle =πr=22/7×7=22m

b. displacement for this route Is the diameter of the circle i.e. 2r=2×7=14m

c. if particle completes the circle then

distance covered by particle=perimeter of whole circle=2π4=2×22/7×7=44m

displacement of particle =2×d (as he has to come back to the point also)=2×14=28 m
