A student must analyze data collected from an experiment in which a block of mass 2M traveling with a speed v0 collides with a block of mass M that is initially at rest. After the collision, the two blocks stick together. Which of the following applications of the equation for the conservation of momentum represent the initial and final momentum of the system for a completely inelastic collision between the blocks? A. 2Mvo = 3Mvf, because the blocks stick together after the collision.
B. 3Mvo = 3Mvf, because the blocks stick together after the collision.
C. 2Mvo = 2Mvf + Mvf, because the blocks stick together after the collision.
D. 2Mvo = Mvf + 3Mvf, because the blocks do not stick together after the collision.
