Inside the wheel, the entire mass m of which can be considered concentrated in the rim, a squirrel runs, and the ratio of the mass of the wheel to the mass M of the squirrel is equal to V2. The wheel rotates without friction around a fixed horizontal axis. The coefficient of friction between the wheel rim and the squirrel is k = 1. What is the maximum constant linear acceleration a the squirrel can impart to the wheel?
