Question

4) A body is moving along a circular path of radius 7m. What is the distance travelled and displacement of the body when it completes half rotation?​

Answer 1

Answer:

distance = 22 m

displacement = 14 m

Explanation:

displacement is the shortest possible distance and here its just the diameter that is the shortest possible path between two diametrically opposite points

distance is half of the circumference i.e, 1/2(2pie)r = (pie)r

                                                                                   = 7*22/7

                                                                                   = 22 m..

Hope it is correct and helpful :)

Answer 2

Answer:

distance is 7 pie., displacement is 14 m

Explanation:

Since there would be only half rotation...

Distance: 2pie r/2 = pie (7m)

Displacement would be the straight line

= 2r = 2(7m)

= 14 m

I hope this helps you, Have a great day.
