An object of mass 0.35kg oscillates in Simple Harmonic Motion with an amplitude of 140mm and a frequency of 0.6Hz; Calculate or find  A) Maximum Kinetic energy of the object  B)Maximum potential energy of the object  C) Potential and Kinetic energy at the midway point between the center and the extremity of the motion.

Two simple harmonic oscillators H1 and H2 of masses on a spring have masses m1 and m2, spring constants k1 and k2, and amplitudes A1 and A2. It is found that the total mechanical energy of H2 equals 4H1. Which one of the following will NOT give this relationship? mị = m2 ; 4k1 = k2 ; A1 = A2 4m1 = m2 ; 4k1 = k2 ; Aı = A2 mi = m2 ; 2kı = k2 ; (v2) A1 = A2 4m1 = m2 ; kı = k2 ; A1 = A2

1) In simple harmonic motion, when is the magnitude of the acceleration the greatest? (There could be more than one correct choice.) A) when the speed is a maximum B) when the displacement is a zero C) when the magnitude of the displacement is a maximum D) when the potential energy is a maximum E) when the kinetic energy is a minimum

A protein dimer can be viewed as a dumbbell linked by a spring. Stretching of the spring with an AFM cantilever adds the total (internal) energy of 10−17 J to the dimer. What is the average kinetic energy of dumbbell oscillations after the external force has been released? Help me
