Question

a particle describes a semicircle of radius l 14m. what are its distance and displacement covered
​

Answer 1

Explanation:

Distance covered is 44 meter and displacement covered is 28 meter

Solution:

Given that,

A particle describes a semicircle of radius 14 m

Radius = 14 m

Distance covered = circumference of semi circle

Distance covered = \pi rπr

\begin{gathered}\text{Distance covered } = \frac{22}{7} \times 14\\\\\text{Distance covered } = 44\end{gathered}

Distance covered =

7

22

×14

Distance covered =44

Thus, distance covered is 44 meter

Displacement = 2r

Displacement = 2(14) = 28

Thus displacement covered is 28 meter

Answer 2

Explanation:

Radius= 14m

So, distance travelled=> πr =>22/7×14= 44m

Now, Displacement => 2r

= 2×14m

= 28m
