An astronaut is being tested in a centrifuge. the centrifuge has a radius of 10 m and, in starting, rotates according to ? = 0.30t2, where t is in seconds and ? is in radians. answers must have units! (a) when t = 12.0 s, what is the magnitude of the astronaut's angular velocity? (b) when t = 12.0 s, what is the magnitude of the astronaut's linear speed? (c) when t = 12.0 s, what is the magnitude of the astronaut's tangential acceleration? (d) when t = 12.0 s, what is the magnitude of the astronaut's radial acceleration?

Power can be defined as a. the distance over which work was done. b. how much work can be done in a given time. c. all the work in an given area. d. the energy required to do work.
