Problem M. 402. (February 2021)

M. 402. Make an 80-cm long paper strip from a thin sheet of paper, and attach its ends at the same height to two movable stands, which are at a certain distance from each other. Place a small size cylinder-shaped unopened tin can on the strip as shown in the figure, and let it roll without initial speed. In the case of different distances of \(\displaystyle d\) between the stands measure the greatest speed of the symmetry axis of the can. At what distance of \(\displaystyle d\) will this speed be the maximum?
