Two blocks collide on a frictionless surface. After the collision, the blocks sticktogether. Block A has a mass M and is initially moving to the right at speed v. Block B has amass 2M and is initially at rest. System C is composed of both blocks. (a) Draw a free-bodydiagram for each block at an instant during the collision. (b) Rank the magnitudes of thehorizontal forces in your diagram. Explain your reasoning. (c) Calculate the change inmomentum of block A, block B, and system C. Anybody want to take a crack at this?

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
