Figure 3 0.5 m/'s 0.9 m/s m M m M before after 2) A block of mass m = 8.0 kg has a speed V and is behind a block of mass M = 16 kg that has a 2) speed of 0.50 m/s. The surface is frictionless. The blocks collide and couple. After the collision, the blocks have a common speed of 0.90 m /s. In Figure 3, the loss of kinetic energy of the blocks due to the collision is closest to: A) 4.3 J B) 2.2 J C) 1.9 J D) 3.8 J E) 2.7 J
