Question

an athlete is running around a circular track radius 350m calculate distance and displacement covered by the athelte in half round solve the full question send me pic please it's very urgent​

Answer 1

Given:

An athlete is running around a circular track radius 350m.

To find:

• Distance and Displacement on half round?

Calculation:

• Distance is defined as a scalar quantity characterized by the total path length travelled by an object in a specified time.

• Similarly, displacement is defined as a vector quantity characterized by the shortest length between the starting and stopping point of the object.

$\rm distance = \dfrac{2\pi r}{2}$

$\rm \implies distance = \pi r$

$\rm \implies distance = \dfrac{22}{7} \times 350$

$\rm \implies distance = 1100 \: m$

Now, displacement :

$\rm \implies displacement = 2r$

$\rm \implies displacement = 2 \times 350$

$\rm \implies displacement = 700 \: m$

So, distance is 1100 metres and displacement is 700 metres.
