In order to move the rectangular stones which built the pyramids the ancient Egyptians used a system of cylindrical logs placed close to each other on the ground which rolled along (without slipping) as the stone on top was pulled by slaves (it also did not slip). If the radii of the logs were all 16 cm and their maximum angular velocity about their axis was 1 radians per second, what was the maximum linear speed (in m/s) of the pyramid stones.
