A sewing machine needle moves with a rapid vibratory motion, rather like SHM, as it sews a seam. Suppose the needle moves 8.4 mm from its highest to its lowest position and it makes 27 stitches in 8.5 s. What is the maximum needle speed?

A large block P executes horizontal simple harmonic motion as it slides across a frictionless surface with a frequency f = 1.7 Hz. Block B rests on it, as shown in the figure, and the coefficient of static friction between the two is ìs=0.64. (b) What is the maximum force of ...

Objects of equal mass are oscillating up and down in simple harmonic motion on two different vertical springs. The spring constant of spring 1 is 186 N/m. The motion of the object on spring 1 has 3 times the amplitude as the motion of the object on spring 2. The magnitude of ...

A sinusoidal transverse wave of amplitude ym = 3.2 cm and wavelength = 3.4 cm travels on a stretched cord. Find the ratio of the maximum particle speed (the speed with which a single particle in the cord moves transverse to the wave) to the wave speed.
