Thank you for the help, I figured out how to do it.

Homework Statement During an earthquake, a floor oscillates horizontally in approximately simple harmonic motion. Assume it oscillates at a single frequency with a period of 0.84 s. After the earthquake, you are in charge of examining the video of the floor motion and discover that a box on...

Ok, I've tried using the equation F = 2*m*r*omega^2 where r = 1/2i. The 2 is there because there are two masses. However, I get an answer of 50.3 1/s^2 which doesn't seem to be right. Am I misapplying the centripetal force? Or is there another force I'm not accounting for?

Homework Statement Suppose that in the figure below, script i = 0.88 m, L = 2.2 m, M = 1.2 kg, and m = 0.6 kg. The string breaks when the system's angular speed approaches the critical angular speed ωi, at which time the tension in the string is 108 N. The masses then move radially outward...

Homework Statement The figure shows the rear view of a space capsule that was left rotating rapidly about its axis at 30 rev/min after a collision with another capsule. You are the flight controller and have just moments to tell the crew how to stop this rotation before they become ill from...

would the translational form of Newton's second law be mgsinθ - Fs = ma then? And if so, I can use Newton's second law for rotation to find that Fs*r = mR^2*a/r getting that ma = Fs Plugging this into the translational form of the equation I would obtain a = 1/2gsinθ. Is that the answer then?

Homework Statement A basketball rolls without slipping down an incline of angle θ. The coefficient of static friction is μs. Model the ball as a thin spherical shell. (Use any variable or symbol stated above along with the following as necessary: m for the mass of the ball and g.) ] a) Find...
