two ants of equal mass are on a disk that rotates at a constant rate. ant a is at a radial position of d, and ant b is at a radial position of 2d. determine (and explain! ) the ratio b: a for their: a. b. c. d. linear velocities angular velocities linear (tangential) acceleration angular acceleration explain which ant would be more likely to develop motion sickness from the spinning, including a discussion of the relevant variables. e.
