Homework Statement
: A centrifuge starts from rest and speeds up at 3400rpm after 50 seconds.a sample is at a distance of 37.5mm from the centre
1) find the angular acceleration
2) calculate the centripetal acceleration [/B]
Homework Equations
:v2 / r
v = rω
a = rω2
a=Λω/Λt
3. The Attempt at a Solution
1) a=Λω/Λt = 3400/60*2∏/50 = 7.12 rad/sec^2
2) ac =v^2/ r = 7.12/ 0.01875 ( 0.01875 is the radius converted to M) [/B]
