A uniform stick, mass m and length l, is placed in a horizontal plane by hanging it from a massless string attached to the center. A ball of mass M moving with speed V in the plane of the stick. The ball strikes the stick at a distance d from the center. the collision is elastic. Find the resulting translational and rotational speeds of the stick and the resulting speed of the ball. show that the relative speed of the ball and the point of contact on the stick is the same before and immediately after the collision.

A stick is resting on a concrete step with 2727 of its total length ?L hanging over the edge. A single ladybug lands on the end of the stick hanging over the edge, and the stick begins to tip. A moment later, a second, identical ladybug lands on the other end of the stick, which results in the stick coming momentarily to rest at ?=41.3∘θ=41.3∘ with respect to the horizontal, as shown in the figure.

A uniform board of length L=.75m is sliding along a smooth, frictionless horizontal plane. The board slides across a boundary with a rough horizontal surface. The coefficient of kinetic friection between the board and another second surface is μk= .31. The board has an initial speed of v=2.5m/s. How far past the boundary is the left end of the board when the board comes to rest? The answer was .654m, but I'm not getting any answer close to it, please...
