Question

the distance travelled by the athlete and (ii) the magnitude of the displacement of the athlete
at the end of 30 sec.

Answer 1

Answer:

Explanation:

Answer:

628.57 metres

0 metres

Explanation:

Given:

diameter of the circular track = 200 metres

Radius of the circular track = = 100 metres

Time taken = 30 seconds

To find:

Distance travelled by the athlete

Displacement at end of 30 seconds

Distance travelled will be equal to the boundary (circumference of the circle)

Circumference of the circle =  

Circumference of the circle =  

Circumference of the circle =  

Circumference of the circle = 628.57 metres

The distance travelled at the end of 30 seconds will be equal to 628.57 metres

At the end of 30 seconds the athlete will come back to the initial position which means displacement =0
