Consider three particles that interact with internal forces given by ? ⃗ _1→2, ? ⃗ _3→1, etc. The total
force on the system is the sum of these internal forces with any external forces
(? ⃗ _i_,_ext , ?ℎ??? ? = 1,2,3). By writing out the sum explicitly, use Newton’s third law to prove that
the total acceleration of the system is only due to the external forces.

In a closed, isolated system of particles, forces internal to the system do not change the motion of the system as a whole. The velocity of the center of mass of such a system is unchanged unless the system is impacted by some net external force. In this context, and with the aid of a single illustration, explain what is meant by a) internal force, and b) external force. c) Explain why internal forces have no effect on the system’s...

Consider three players (1, 2, 3) and three alternatives (A, B, C). Players vote simultaneously for an alternative and abstention is not allowed.The alternative with more votes wins. If no alternative receives a majority, alternative A is chosen. U1 (A) = U2 (B) = U3 (C) = 2 U1 (B) = U2 (C) = U3 (A) = 1 U1 (C) = U2 (A) = U3 (B) = 0 Obtain all Nash equilibria in pure strategies.

Consider a city with three consumers: 1, 2, and 3. The city provides park land for the enjoyment of its residents. Parks are a public good, and the amount of park land (which is measured in acres) is denoted by z. The demands for park land for the three consumers are as follows: D1 =40–z, D2 =30–z, D3 =20–z. These formulas give the height of each consumer’s demand curve at a given level of z. Note that each demand curve...
