An ultracentrifuge accelerates from rest to 100,000 rpm in 2.00 min.

(a)What is its angular acceleration in rad/s²? rad/s²

(b)What is the tangential acceleration, in m/s², of a point 10.55 cm from the axis of rotation? m/s²

(c)What is the radial acceleration, in m/s², of this point at full rpm? m/s²

(d)Express this radial acceleration as a multiple of g. g
