Answer:

The circular path has a radius of 1 km, with O as the center and R as the distance between the two points.

The biker is moving at a speed of 10 meters per second.

As a result, it is possible to say that the motion is a uniform circular motion at the point R.

As a result, R = 1000 metres.

v = 10 metres per second

Therefore, acceleration, ac = v

^{2}/R = 0.1 m/s^{2}along RO.
