A potter's wheel (a solid, uniform disk) of mass 6.0kg and radius R spins about its central axis with 5.0 rad/s. A 2.0kg lump of clay is dropped onto the wheel and sticks at the edge, decreasing its angular speed. Find the new angular speed of the system.

a. 3.0 rad/s

b. 6.0 rad/s

c. 2.0 rad/s

d. 3.5 rad/s

e. 2.5 rad/s

L1=L2
I1*ω1=Ι2*ω2
do you know how to calc inertia (I1 and I2)?
