Answer 2

Given,

Distance covered by a body along a semicircular path = 5m

To Find,

The ratio of distance to displacement.

Solution,

Since we are given the distance traveled by the body = 5m so we need to calculate the displacement of the body

Displacement of the body = 2r, where r is the radius of the semicircle.

Now,

πr = 5

r = 5/π = 5*7/22 = 35/22

Now,

2r = 2(35/22) = 35/11

So, the ratio of distance to displacement will be,

Distance:Displacement =  5:35/11

                                        = 11:7

Hence, the ratio of distance to displacement is 11:7.
