A blоck оf mаss m = 34 kg аnd speed V is behind а blоck of mass M = 81 kg and speed of 0.51 m/s as shown in the figure. The surface is frictionless and the blocks collide and couple. After the collision, the blocks have a common speed of 0.90 m/s. What is the magnitude of the impulse on the 34-kg block due to the collision?
