Question

A particle moves in a circle of diameter 5m caluclate the distance and displacement after it complete 3and half round

Answer 1

Answer:

Distance =68.75m

Displacement =5m

Step-by-step explanation:

Distance=3.5×pi×r×r

Radius = diameter /2=2.5

Distance =3.5×22/7×2.5×2.5

=68.75m

Displacement at end of 3 and half round will be the diameter = 5m

Distance =68.75m

Displacement =5m

Answer 2

Step-by-step explanation:

Aloha !

Let S be the displacement of body.

And D be the distance of the body.

Given, Diameter = 5m

Such that Radius= 5/2=2.5m

Distance = 3½×π×r²

D= 3½×22/7×2.5×2.5

Where we can take the value of π had 22/7 or 3.14

D= 22/2×2.5×2.5

D= 11×2.5×2.5

D=27.5×2.6

D=68.75 m
