To measure the magnitude of the acceleration due to gravity g in an unorthodox manner, a student places a ball bearing on the concave side of a flexible speaker cone ( Figure 1). The speaker cone acts as a simple harmonic oscillator whose amplitude is A and whose frequency f can be varied. The student can measure both A and f with a strobe light. Take the equation of motion of the oscillator as y(t) = A cos (wt + p), where w 2πf and the y axis points upward. If the ball bearing has mass m, find N (t), the magnitude of the normal force exerted by the speaker cone on the ball bearing as a function of time. Your result should be in terms of A, either f (or w), m, g, a phase angle o, and the constant . ► View Available Hint(s) N (t) = IVE ΑΣΦ ?
