Question: An ultracentrifuge accelerates from rest to 100,000 rpm in 2.00 min.
a. What is its angular acceleration in rad/s2?.
b. What is the tangential acceleration (in m/s2) of a point 10.00 cm from the axis of rotation?
c. What is the radial acceleration in m/s2? and in multiples of g of this point at full rpm?
