Gear 1, under the influence of torque M, drives gear 2 (see figure). Gear 2 is rigidly connected to pulley 3, on which a thread is wound, carrying a load m. The gears and pulley are weightless; there is no friction. Find the speed of the load at the moment when it covered the distance s. The radii of the gears are equal to R1 and R2, the radius of the pulley is equal to r, and the initial speed of the load is zero.
