Homework Statement
A device with 8 balls each with a mass of 0.8 kg is attached to spokes with length of 1.4 m, radius of 0.7 m. A lump of clay of 0.2 kg falls on the at the location shown and is attached to a ball at 45 degree angle. Before the impact, the clay was at a speed of 5 m/s. It moves counterclockwise with a angular speed of 0.08 radians/s.
What is the angular momentum of the system of the clay and devise?
Homework Equations
Ldevice = 1/2*M*R2
Lclay = r*p
Lsystem = Ldevice + Lsystem
The Attempt at a Solution
For the device, is the mass 8*0.08?
Also for the clay, is r just the radius?
Is this the right way to do this?
