Ahamster sits 0.10 m from the center of a lazy susan of negligible mass. the wheel has an angular velocity of 1.0 rev/ s. how will the angular velocity of the lazy susan change if the hamster walks to 0.30 m from the center of rotation? assume zero friction and no external torque. a. it will speed up to 2.0 rev/s. b. it will speed up to 9.0 rev/s. c. it will slow to 0.01 rev/s. d. it will slow to 0.02 rev/s.

C. It will slow to 0.1 rev/s.

Explanation:

As we know that there is no external torque on the system

so here angular momentum must be conserved

so we will have

here initially he is at distance of r = 0.10 m from the center

so we have

now when he walks to distance of r = 0.30 m from center then

now we have

i wanna say it’s between b and d, leaning more towards b.

okay i have so many questions. but the big one here is: um wt..f is this mess? ?
