Question
The rotating drum in a clothes-dryer has a radius of $0.31 \mathrm{~m}$. If the acceleration at the rim of the drum is $27 \mathrm{~m} / \mathrm{s}^{2}$, what is the tangential speed of the rim?
Step 1
Step 1: We start with the centripetal acceleration equation, which is given by: \[a = \frac{v^2}{r}\] where \(a\) is the centripetal acceleration, \(v\) is the tangential speed, and \(r\) is the radius of the rotating drum. Show more…
