Task id13305
Block 1 lies on the same block 2 (Figure a). Both of them as a whole slide along a smooth horizontal surface with a speed v0 and collide with a similar stationary block 3. The impact of block 2 on block 3 is absolutely inelastic (blocks 2 and 3 stick together, Figure b). What is the length of the bars l if it is known that block 1 stopped moving relative to bars 2 and 3 due to friction after it completely moved from 2 to 3? The coefficient of friction between bars 1 and 3 is equal to k. Friction on top
