An astronaut is being tested in a centrifuge. the centrifuge has a radius of 9 m and, in starting, rotates according to ? = 0.30t2, where t is in seconds and ? is in radians.

(a) when t = 9.0 s, what is the magnitude of the astronaut's angular velocity?

(b) when t = 9.0 s, what is the magnitude of the astronaut's linear speed?

(c) when t = 9.0 s, what is the magnitude of the astronaut's tangential acceleration?

(d) when t = 9.0 s, what is the magnitude of the astronaut's radial acceleration?
