Question

A wheel rotates at a constant angular velocity of 30.0 rpm. What is its angular velocity in rad/s? (3.14 rad/s) Through what angle (in radian) will the wheel rotate in 60.0 s? (188.4 rad/s) How long will it take the wheel to make one complete rotation (2 ?? radians)? (2.0 s) A flywheel rotating with constant angular acceleration of 0.6 rad/s² has an initial angular velocity of 1.5 /s. What is its angular velocity at t = 4.5 s? (4.2 rad/s) Through what angle has the wheel turned between t = 0 s and t = 4.5 s? (12.82 rad) A disc of 2.0 kg and radius 15 cm rotates about an axis passing through its center and perpendicular to planes. It makes 2 revolution per second. lculate: Moment of inertia. (0.0225 kg m²) Kinetic energy of rotation. (1.77 J) Angular momentum. (0.28 kg m²/s)
