A block of mass m = 2 kg has a speed v and is behind a block of mass m = 44 kg that has a speed of 0.5 m/s. the surface is frictionless. the blocks collide and couple. after the collision, the blocks have a common speed of 0.9 m/s. in fig. 8.2, the impulse on the 2-kg block due to the collision is closest to:
