A person wants to make a metronome for music practice. He uses a 32 gram object attached to a spring to serve as the time standard. What is the desired spring constant for the spring if the object needs to make 1 vibration each second? Assume that the spring obeys Hooke's Law and ignore any possible damping due to air resistance or friction.
