Answer 1

Answer:

hope the answer helps you

Answer 2

Answer:

$\bf \huge \underline {\underline{Answer}}$

$\huge{\textsf{→}}$ Half round: distance= 628 metres, displacement = 400 metres

$\huge{\textsf{→}}$ One round: distance = 1256 metres, displacement = 0 metres

Explanation:

Given:

$\huge{\textsf{→}}$ Radius of the circular track = 200 metres

To find:

$\huge{\textsf{→}}$ Distance and displacement in:

$\huge{\textsf{→}}$ Half round

$\huge{\textsf{→}}$ One complete round

Distance:

$\huge{\textsf{→}}$ The circumference of the circle will be the distance covered in one round whereas half of the circumference will be distance covered in half roun

Half round:

$\huge{\textsf{→}}$ Circumference of circle =

$\huge{\textsf{→}}$ Circumference of semicircle =

$\huge{\textsf{→}}$ Distance = 3.14×200

$\huge{\textsf{→}}$ Distance = 628 metres

$\huge{\textsf{→}}$ the distance covered in half round is equal to 628 metres

One round:

$\pink{\textsf{→}}$ Distance =

$\pink{\textsf{→}}$ Distance = 2×3.14×200

$\pink{\textsf{→}}$ Distance = 1256 metres

$\huge{\textsf{→}}$ The distance covered in one round is equal to 1256 metres

Displacement:

Half round:

$\huge{\textsf{→}}$ The displacement at the half round will be equal to the diameter of the circle

$\pink{\textsf{→}}$ Diameter = 2×Radius

$\pink{\textsf{→}}$ Diameter = 2×200

$\pink{\textsf{→}}$ Diameter = 400 metres

$\huge{\textsf{→}}$ The displacement at end of half round will be equal to 400 metres

One round:

$\huge{\textsf{→}}$ The displacement will be equal to 0 as the athlete will come to initial position
