A 4.4-cm-diameter, 24 g plastic ball is attached to a 1.2-m-long string and swung in a vertical circle. The ball's speed is 6.7 m/s at the point where it is moving straight up. What is the magnitude of the net force on the ball? Air resistance is not negligible. Express your answer with the appropriate units. ► View Available Hint(s) Fnet = Submit μA Value Previous Answers Units ?

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
