Problem 6-23 Centripetal force - Part 2 - C

A child has tied a piece of wood of mass \(0.47\; kg\) to a string and is swinging it in a vertical circle of radius \(83\; cm\). At the top of the circle:

(a) draw a free body diagram for the wood,
(b) determine the magnitude of the tension in the string, if the speed of the wood is \(3.7 \;m/s\).

Accumulated Solution

FBD with forces and directions indicated

No. From the FBD, both \(T\) and \(mg\) act in the same direction.

Try again.
