Question

A body is moving along a circular path of radius 10m , calucate the distance travelled by the body after completion of two rounds

Answer 1

Answer:

Given:

Radius of circular path = 10 m

Number of rounds completed = 2 rounds.

To find:

Distance travelled

Concept:

Distance refers to the actual path length travelled by the object in a specified time interval. It's an scalar Quantity having only magnitude and no directions.

Distance shall always be positive and never be negative . It is always greater or equal to displacement (which is an vector)

Calculation:

Distance will be equal to two times the circumference of the Circular path :

$distance = 2 \times (2\pi r)$

$= > distance = 2 \times (2 \times \pi \times 10)$

$= > distance = 40\pi \: m$

Putting value of π = 22/7 , we get :

$= > distance = 40 \times \dfrac{22}{7}$

$= > distance = 125.66 \: m$

So final answer :

$\boxed{ \huge{ \bold{distance = 125.66 \: m}}}$

Given,.

Radius=10m

Distance=2×2πr

=2×2×π×10

=4×π×10

=40×π

=40×22÷7

=125.67
