... Picture the Problem. We can find the velocity of the center of mass from the definition of the total momentum of the system. We’ll use conservation of energy to find the maximum compression of the spring and express the initial (i.e., before collision) and final (i.e., at separation) velocities. Fin ...

Solutions
... The energy surplus in the tropics is constant, from part (b), and the energy deficit is constant; therefore, the same amount of energy is being redistributed from the tropics to the polar regions by the poleward energy transport. This question was meant to illustrate that the energy surplus (and not ...

... The internal energy (E) of a system is the sum of KE and PE of all particles in the system. The internal energy of a system can be changed by a flow of work, heat, or both. i.e. ΔE = q + w ΔE: change of E, q: heat, w: work Thermodynamic quantities always consist of two parts: a number, giving the ma ...
