Question 1
A hollow cylinder rotates about its center. Calculate the final angular speed if a net torque of 10 N m is applied for 3 seconds given its moment of inertia is 4 kg m².
💡 Hint: Use the relationship between torque, moment of inertia, and angular acceleration.
Question 2
Explore a spinning record; if it has an angular momentum of 12 kg m²/s when the radius decreases to half, what is the new angular speed?
💡 Hint: Think about how radius affects moment of inertia.
