What is the difference between the equations F=kx, F=-kx, and F=1/2kx^2 in spring problem situations?
Consider the equation for a spring: d x(t) F = -kx = ma = mdt2 where This reduces to dax(t) +w2x(t) = 0 at² a) Verify that X(t) = Acos(wt + 1/2) is a solution by direct substitution. (2pts) b) Prove that Total Energy is conserved. (4pts) c) Prove that F is a restoring force to the equilibrium point x=0.(4pts)
