A block of mass 15 kg is sliding along the ice at a constant speed of 4.0 m/s. Just ahead of it is a block of mass 23 kg sliding in the same direction at a constant speed of 3.6 m/s. When the two blocks collide, the 23 kg block travels at a new speed of 5.2 m/s. What is the new speed of the 15 kg block?
