Unformatted text preview: ce Ko/ ILlEI = 5.27, five complete crossings are made, leaving the block with energy Ko. - 5j..6.EI = 0.113 J on the curved rise side. This remaining energy is sufficient to move the block a distance s = 0.113 J ..;J-tkmg = 22.5 em towards point 0, so the block comes to rest 85 - 22.5 = 62.5 ern to the right of point O. g slides back and forth in a hemispherical lof 11 cm radius, starting from rest at the as shown in Fig. 8-40. The bowl is frictionless pt for a L5-cm-wide sticky patch at the tom, where the coefficient of friction is 0.6l. ,",many times does the bug cross the sticky Jf6 5""''1
