## Homework Statement

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 move vertically in simple harmonic motion. Whether the “bull” has a rider or not, it moves with the same amplitude 2.13 m and frequency 0.385 Hz. Being from Texas you decide to ride it the “macho” way by NOT holding on. To no ones surprise you go flying out of the saddle. While waiting for your bruises and pride to heal, you decide to calculate how fast upward you were moving when you left the saddle.

## Homework Equations

V(ox) = -[tex]\varpi[/tex]*A*sin[tex]\phi[/tex]

## The Attempt at a Solution

I notice it is a simple harmonic motion question so I am using the equation relative to SRH velocities. Since it is a vertical motion, the gravity and mass play a role in the velocity. The angle I understand to be zero degrees?

I first found angular frequency by taking 2*pi*frequency. Then multiplied it by amplitude to get 5.15. The answer is 3.18. I know there is something small i'm missing, probably the mass factor, but i've been stuck for a while and could use some help....
