Gravity holds the system together
Answer:
The solved problem is in the photo. Hope it helps.
Answer:
ω = 1.83 rad/s clockwise
Explanation:
We are given:
I1 = 3.0kg.m2
ω1 = -5.4rad/s (clockwise being negative)
I2 = 1.3kg.m2
ω2 = 6.4rad/s (counterclockwise being positive)
By conservation of the momentum:
I1 * ω1 + I2 * ω2 = (I1 + I2) * ω
Solving for ω:

Since it is negative, the direction is clockwise.
I believe you mean 6.02*10^7 but you want to shift the decimal 7 times to the right which would be 60200000 (:
