A $1\mathrm{.}3-$m$-$diameter, $1\mathrm{.}2-$m$-$high garbage can is found in the morning tipped over due to high winds during the night. Assuming the average density of the garbage inside to be $\backslash (150\backslash$mathrm$\{$~kg$\}/\backslash$mathrm$\{$m$\}^\{3\}\backslash )$ and taking the air density to be $\backslash (1\mathrm{.}25\backslash$mathrm$\{$~kg$\}/\backslash$mathrm$\{$m$\}^\{3\}\backslash ),$ estimate the wind velocity during the night when the can was tipped over. Take the drag coefficient of the can to be $0\mathrm{.}7.$

The wind velocity during the night when the can was tipped over is $\backslash (\backslash$mathrm$\{$km$\}/\backslash$mathrm$\{$h$\}\backslash ).$
