A bullet of mass m is fired with a horizontal velocity v0 and at a height h = 12R into a wooden disk of much larger mass M and radius R. The disk rests on a horizontal plane and the coefficient of friction between the disk and the plane is finite. a) Determine the linear velocity (~v1)G and the angular velocity ω1 of the disk immediately after the bullet has penetrated the disk b) Describe the ensuing motion of the disk and determine its linear velocity after the motion has become uniform.
