2 Activity: Application The Spinning Terror ride The spinning terror is a large vertical drum which spins so fast that everyone stays pinned to the wall when the floor drops out. For a typical ride the radius of the drum is 2 m. What is the minimum angular velocity if the coefficient of friction between the patron and the wall is 0.3?

6 Mass on a spring: initial conditions
7 Application example: Falling through a viscous fluid Assume that the density of the fluid is very small compared to the density of the falling object. (e.g – a human body in air) Assume that the body falls under the action of constant gravity and drag force only. Assume that the drag force is linear in speed: Is there a terminal velocity? If there is, find the terminal velocity.
