In Fig. 10-34, three 0.0100 kg particles have beenglued to a rod of length and negligible mass and can rotate around a perpendicular axisthrough point O at one end. How much work is required to change therotational rate (a) from 0 to 20.0 rad/s, (b) from 20.0 rad/s to40.0 rad/s, and (c) from 40.0 rad/s to 60.0 rad/s? (d) What is the slope of a plot of the assembly's kinetic energy (in joules) versusthe square of its rotation rate (in radians-squared persecond-squared)?
