an ultracentrifuge accelerates from rest to 100,000 rpm in 2.00 min. (a) what is the average angular acceleration in rad/s2? (b) what is the tangential acceleration of a point 9.50 cm from the axis of rotation? (c) what is the centripetal acceleration in m/s2 and multiples of g of this point at full rpm? (d) what is the total distance traveled during the acceleration by a point 9.5 cm from the axis of rotation of the ultracentrifuge?
