A 20cm radius turn-table is turning with a constant angular speed ω0=33rev/min .  The turn-table has a moment of inertia I=5.0kg(cm)2 relative to the axis through its center.  Call this central axis the z-axis.  A piece of sticky gum with mass m=50g falls straight down on the turn-table and sticks at a distance of 10cm from the center. What are the forces the tact on the system after the gum falls on the turn-table? (Choose one) a)Weight of gum b)Weight of turn-table, Normal force on the turn-table, Weight of gum, Normal force on gum c)Weight of turn-table, Weight of gum   What is the moment of inertia of the system after the gum falls on the turn-table? (Choose one) 15 kg cm2 10 kg cm2
