Centripetal Force Calculation: How Many G's Can Your Centrifuge Simulate?

[JarrettHayama]

#1 Round and round we go! You are constructing a centrifuge to use its spinning motion to act like increased gravity.
(a) Find the formula for centripetal force.
(b) Your centrifuge can spin at 35,000 rpms and your samples are placed 1.75 inches from the center of rotation. If the force of gravity is g = 9.81m/s2, how many times the force of gravity can your centrifuge simulate?

That last bit should read, "If the acceleration due to gravity is..."
