Question

A chimney (length 17 m, mass 499 kg] cracks at the base and topples. Assume: - the chimney behaves like a thin rod, and does not break apart as it falls. - only gravity (no friction) acts on the chimney as it falls. - the bottom of the chimney pivots, but does not move. Find the linear speed of the very top of the chimney, in m/s, just as it hits the ground.
