Question

an athlete goes around a circular track of radius 7m.what is the total distance covered by him and displacement
please answer immediately ​

Answer 1

Answer:

Distance = 43.96 metres

Displacement = 0 metres

Explanation:

Given:

• Radius of the circular track = 7 metres

To find:

• Distance covered by the athlete
• Displacement covered by the athlete

Distance:

Distance covered by the athlete will be equal to the circumference of the circular track

Distance = $2 \pi r$

Distance =$2 \times 3.14 \times 7$

Distance =6.28×7

Distance = 43.96 metres

The distance covered by the athlete is equal to 43.96 metres

Displacement:

Displacement  will be equal to 0 as the athlete returns back to the initial position after covering a round
