Δθ and Δt are equal for both ladybugs.
Two ladybugs sit on a rotating disk, as shown in the figure (the ladybugs are at rest with respect to the surface of the disk and do not slip). (Figure 1) Ladybug 1 is halfway between ladybug 2 and the axis of rotation.
What is the angular speed of ladybug 1?
a. one-half the angular speed of ladybug 2
b. the same as the angular speed of ladybug 2
c. twice the angular speed of ladybug 2
d. one-quarter the angular speed of ladybug 2
What is the direction of the vector representing the angular velocity of ladybug 2? See the figure for the directions of the coordinate axes.
