Simple Harmonic Motion
While visiting friends at Cal State Chico ,you pay a visit to the Crazy Horse Saloon . This fine establishment features a 200-kg mechanical bucking bull , that has a mechanism that makes it moves vertically in simple harmonic motion . Whether the “bull” has a rider or not , it moves with the same amplitude 25 cm. You watch and notice that in a 10-s interval . It makes 15 oscillations . After watching other saloon patrons hold on the “bull” while riding , you decide to ride it the macho way by not holding on . No one is terribly surprised when you come out of the saddle Later , while waiting for your bruises and pride to heat, you pass the time by calculating at what point in the bull’s cycle you lose contact .
