The centripetal acceleration of the runner and the agent which exerts the
Answer to Problem 12PP
The centripetal acceleration of the runner is
Explanation of Solution
Given:
Speed of the runner
Radius of the curve,
Formula used:
Centripetal acceleration:
Here, v is velocity and r is the radius.
Calculation:
Now, put the value of v and r and solve:
Conclusion:
Therefore, the centripetal acceleration of the runner is
Force of friction of the track which is acting on the shoes of the runner is responsible for centripetal force on the runner.
