Physics

A beetle with a mass of 25.0 g is initially at rest on the outeredge of a horizontal turntable that is also initially at rest. Theturntable, which is free to rotate with no friction about an axisthrough its center, has a mass of 80.0 g and can be treated as auniform disk. The beetle then starts to walk around the edge of theturntable, traveling at an angular velocity of 0.0700 rad/sclockwise with respect to the turntable. (b) With respect to you,motionless as you watch the beetle and turntable, what is theangular velocity of the beetle? Use a positive sign if the answeris clockwise, and a negative sign if the answer iscounter-clockwise. rad/s (c) What is the angular velocity of theturntable (with respect to you)? Use a positive sign if the answeris clockwise, and a negative sign if the answer iscounter-clockwise. rad/s (d) If a mark is placed on the turntableat the beetle's starting point, how long does it take the beetle toreach the mark again?
