Concept explainers
A 70-kg person sits on the edge of a horizontal rotating platform 2 m from the center of the platform and has a tangential speed of 3 m/s. Calculate the
Frictional force.
Answer to Problem 26A
Explanation of Solution
Given:
Mass of the person,
Tangential velocity,
Distance of person from the center of the platform,
Formula Used:
The equation for centripetal force is,
Where,
Calculation:
When the person rotates with horizontal platform in the circular path, the friction force that keeps the person in place is equal to the centripetal force. So,
Conclusion:
Therefore, the frictional force is
