What is the astronauts radial acceleration

Reference no: EM13296929

An astronaut is being tested in a centrifuge. The centrifuge has a radius of 12.0 m and, in starting, rotates according to ? = 0.31t2, where t in seconds gives ? in radians. a. When t = 5.0 s, what are the astronaut's angular velocity? b. When t = 5.0 s, what is the astronaut's linear speed? c. When t = 5.0 s, what is the astronaut's tangential acceleration (magnitude only)? d. When t = 5.0 s, what is the astronaut's radial acceleration (magnitude only)?
