Question 591
What is the rotational kinetic energy of a body with I = 2 kg m² and ω = 5 rad/s?
Question 592
A wheel starts from rest and undergoes constant angular acceleration of 4 rad/s² through 5 rad. What is its final angular velocity?
Question 593
What is the angular displacement when 1.5 m of cord is unwound from a wheel of radius 0.3 m?
Question 594
A steady force of 30 N pulls a cord wound around a flywheel. If 1.5 m of cord is unwound, what is the work done?
Question 595
When no external torque acts on a rotating system, what happens to its angular momentum?
