Question 1
A flywheel spins at an initial angular velocity of 25 rad/s and increases to 45 rad/s over 4 seconds. Calculate the angular acceleration.
π‘ Hint: Apply the formula for angular acceleration directly.
Question 2
In an engineering scenario, an angular system experiences a torque of 10 NΒ·m, resulting in an angular acceleration of 2 rad/sΒ². What is the moment of inertia of this system?
π‘ Hint: Recap the relationship between torque, moment of inertia, and angular acceleration.
