Walker, Halliday & Resnick β Rotation: Problem 62
62 In Fig. 10-25, three 0.0100 kg particles have been glued to a rod of length L = 6.00 cm and negligible mass and can rotate around a perpendicular axis through point O at one end. How much work is required to change the rotational rate (a) from 0 to 20.0 rad/s, (b) from 20.0 rad/s to 40.0 rad/s, and (c) from 40.0 rad/s to 60.0 rad/s? (d) What is the slope of a plot of the assemblyβs kinetic energy (in joules) versus the square of its rotation rate (in radians-squared per second-squared)?
