Unformatted text preview: its initial position with half its initial speed. Show that the coe±cient of kinetic friction is μ k = 3 5 tan θ . 4 Problem 4 A bug lands on top of the frictionless, spherical head of a bald man. It begins to slide down his head. Show that the bug leaves the head when it dropped a vertical distance one-third the radius of the head. 1 Physics 8A: Midterm 1 Review 2 5 Probelm 5 A bug slide back and forth in a bowl 11 cm deep, starting from rest at the top. The bowl is frictionless except for a 1.5-cm-wide sticky path on its Fat bottom, where the coe±cient of friction is 0.61. How many times does the bug cross the sticky region?...
