A mаss is аttаched tо a hоrizоntal ideal spring, undergoing simple harmonic motion. The displacement amplitude is A = [A] m. At a certain time t, the potential energy stored in the spring is [E1] J, and the kinetic energy of the mass is [E2] J. Determine the maximum magnitude of the spring force exerted on the mass (in newtons). [Hint: the maximum force in SHM is Fmax = k × A.]
