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 ?

In the arrangement shown in the figure below, an object of mass m = 2.0 kg hangs from a cord around a light pulley. The length of the cord between point P and the pulley is L = 2.0 m. (Ignore the mass of the vertical section of the cord.) The left end of a horizontal cord of density ? is connected to a vibrator at point P. A distance L from point P, the cord goes over a pulley and hangs down. A block of mass m connects to the hanging end of the cord.
