Problem 6-23 Centripetal force - Part 2 - B

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

No. From the FBD, both $T$ and $mg$ act in the same direction.

Try again.
