+		They determined the coefficient of static friction of a banana peel and found it to be almost 6x as slippery as the floor, with <InlineEquation equation=" \\mu_s "/>= 0.066! 
+		They also examined other fruit peels and found apples have a <InlineEquation equation=" \\mu_s "/> of 0.125, orange peels have a <InlineEquation equation=" \\mu_s "/> of 0.198, and tangerine peels are the least slippery with <InlineEquation equation=" \\mu_s "/> = 0.225.
