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.[Answer: 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?
