Q6: Consider a system of two objects of mass M. The two objects are
attached to two springs with spring constants x (see Figure). The interaction
force between the masses is represented by a third spring with spring constant
K12, which connects the two masses.
Determine the eigenfrequencies, eigenvectors, and normal coordinates.

Two particles, each of mass m, are connected by a light inflexible string of length l. The string passes through a small smooth hole in the centre of a smooth horizontal table, so that one particle is below the table and the other can move on the surface of the table. Take the origin of the (plane) polar coordinates to be the hole, and describe the height of the lower particle by the coordinate z, measured downwards from the table surface. Here, the total force acting on the mass which is on the table is -T r^ (r hat). Why?
You are designing an RPG (role-playing game) for a gaming console and have decided to use an open world design, where players can explore the terrain freely, encountering enemies by chance. 8. Your design team has coded this in-game world to exist on the circle x² + y? < 900 Page 3 on the xy-plane. At any point (x, y) in this world you've also associated a danger function d(x, y) that measures how likely it is to encounter an enemy at that point. Thus high values of d(x,y) correspond to dangerous points, while low values of d(x, y) correspond to safe points. If d(x, y) = e¬a²y, find the safest point(s) and most dangerous point(s) in-game.

Disclaimer: if this problem is chosen for the mini-exam, the given function may be different, but will be chosen from the exponential, trigonometric, or polynomial families. * There are two particles (1 and 2) that are moving around in space. The mass of particle 1 is m1 and the mass of particle 2 is m2. The particles are isolated so that only the forces between the particles are significant. The force that 2 exerts on 1 is given by: 2.
