Problem: Blocks A and B are moving toward each other on a horizontal frictionless surface. Block A has mass 5.0 kg and is moving to the right with speed 8.0 m/s. Block B has mass 15.0 kg and is moving to the left with speed 4.0 m/s. The two blocks collide and stick together. After the collision, the combined object (mass 20.0 kg) has velocity A) 0.50 m/s to the left B) 0.50 m/s to the right C) 1.0 m/s to the left D) 1.0 m/s to the right E) 2.5 m/s to the left F) 2.5 m/s to the right G) none of the above answers
