The figure belоw shоws а view frоm аbove of two blocks thаt can slide freely on a frictionless table. The blocks are made of a very hard, non-sticky material. Block A has a speed of 3.0 m/s and is moving toward Block B, which is initially at rest. The blocks collide. After the collision, block A has a velocity vx = -1.0 m/s (where the x-axis is defined as in the diagram). If block A has a mass of 2.0 kg, what is the mass in kg of block B? Use any reasonable assumption about the collision that allows you to solve for the mass.
