The position of a .64 kg mass undergoing simple harmonic motion is given by x(t) = (.16 m)cos([tex]\pi[/tex]t/16). What is the maximum net force on the mass as it oscillates? (hints: First, match the quantities in the equation above to x(t) = Acos([tex]\omega[/tex]t). Next, recall that the max. net force equals the product of the mass and the maximum acceleration.) * 3.9 x 10-3 N * 9.9 x 10-3 N * 1.3 x 10-3 N * 6.3 N I don't really understand this problem and I need some help. So if anyone would be willing to help, I would really appreciate it. Where do I begin?
