**Part A**

Angular velocity:

$\overline{){\mathbf{\omega}}{\mathbf{=}}\frac{\mathbf{\u2206}\mathbf{\theta}}{\mathbf{\u2206}\mathbf{t}}}$

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.

Part A

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

Part B

What is the direction of the vector representing the angular velocity of ladybug 2? See the figure for the directions of the coordinate axes.

a. +x

b. -x

c. +y

d.-y

e. +z

f. -z
