Question

While visiting friends at Cal State Chico, you pay a visit tothe Crazy Horse Saloon. This fine establishment features a 200- kgmechanical bucking bull that has a mechanism that makes it movevertically in simple harmonic motion. Whether the“bull” has a rider or not, it moves with the sameamplitude 2.24 m and frequency 0.400 Hz. Being from Texas youdecide to ride it the “macho” way by NOT holding on. Tono ones surprise you go flying out of the saddle. While waiting foryour bruises and pride to heal, you decide to calculate how fastupward you were moving when you left the saddle.

Give your answer in m/s to the second decimal place.

Explanation / Answer

Calculate angular velocity = 2f = (2)*(0.4) = 2.513 rad/s Since the bull would be at maximum velocity when I am launchedoff vm = xm = 2.513 * 2.24 = 5.629 m/s Thrown off at 5.63 m/s to the 2ndd.p
