You are designing a centrifuge to spin at a rate of 13,810 rev/min.
(a) Calculate the maximum centripetal acceleration that a test-tube sample held in the centrifuge arm 14.1 cm from the rotation axis must withstand.
249167 m/s2.
(b) It takes 1 min, 16 s for the centrifuge to spin up to its...
Homework Statement
Express your answer in part (a) in terms of magnitude and angle counterclockwise from the + x direction.
Vector = -25.3i-1.2j
Homework Equations
arctan(ady/adx)
The Attempt at a Solution
Arctan(-1.2/25.3)=2.72
This is wrong... but I have no idea how to fix it.
