An insect of mass m walks with constant speed v0 in a circular path of radius b on a rotating disk with constant angular velocity w. Describe the motion in a coordinate system fixed to the turntable. Calculate the acceleration r'' of the insect with respect to the outside. In particular, calculate r'' for the cases: v0 = bw and v0 = −bw. Note that in the second case the insect is stationary with respect to the outside.
