Problem M. 398. (October 2020)

M. 398. Measure the rolling resistance between a cylinder and the ground. Use two different cylinders of the same radius and carry out the measurement for two different surfaces. (The two different cylinders can be for example a paper cylinder of a roll of plastic wrap, and an aluminium foil roll, whilst the two different surfaces can be the floor of the room with and without a soft carpet.) Investigate how much the deceleration of the cylinder can be considered constant.
