An astronaut is being tested in a centrifuge. The centrifuge has a radius of 9.50 m and, in starting, rotates according to θ = 0.110t2, where t is in seconds and θ is in radians. When t = 3.90 s, what are the magnitudes of the astronaut's (a) angular velocity, (b) linear velocity, (c) tangential acceleration, and (d) radial acceleration?
