In 1994, susan williams of california blew a bubble-gum bubble with a diameter of 58.4 cm. if this bubble were rigid and the centripetal acceleration of the equilateral points of the bubble were 8.5*10^-2 m/s^2, what would the tangential speed of those points be?

0.158 m/s

Explanation:

The centripetal acceleration of the equilateral points of the bubble is given by

$a=\frac{v^2}{r}$

where

v is the tangential speed

r is the radius of the bubble

In this problem, we have:

$a=8.5\cdot 10^{-2} m/s^2$ is the centripetal acceleration

d=58.4 cm is the diameter of the bubble, so the radius is

$r=\frac{58.4 cm}{2}=29.2 cm=0.292 m$

Therefore, we can re-arrange the previous equation to find the tangential speed of the equilateral points:

$v=\sqrt{ar}=\sqrt{(8.5\cdot 10^{-2} m/s^2)(0.292 m)}=0.158 m/s$
