Newton's second law problem. The spring constant can be determined from the balance of forces in equilibrium. Suppose the spring extends a distance LaTeX: \Delta Δ x when additional mass LaTeX: \Delta Δ m is added. Write down Newton's second law for this case and solve for k.[ K=delta m g/delta x.] Make sure you understand how this formula was derived. If delta m=41 g and delta x=6cm, what is k?

A47.2 g block of copper whose temperature is 480 k is placed in an insulating box with a 91.8 g block of lead whose temperature is 200 k. (a) what is the equilibrium temperature of the two-block system? (b) what is the change in the internal energy of the two-block system between the initial state and the equilibrium state? (c) what is the change in the entropy of the two-block system? the heat capacities of copper and lead are 386 j/kg·k and 128 j/kg·k, respectively.
