A counterclockwise torque is suddenly applied to a rotating shaft with a moment of inertia of 5 kg•m2 . The shaft was initially at rest (zero speed). If the applied torque causes the shaft to rotate at a constant angular acceleration of 1.5 rad/s2 , considering zero viscous damping: a) Calculate the applied torque. b) Calculate the angular speed of the shaft after 5 seconds in radians per second. c) Express the speed in revolutions per minute.

A wheel is rotating freely at angular speed 600 rad/s on a shaft whose rotational inertia is negligible. A second wheel, initially at rest and with three times the rotational inertia of the first, is suddenly coupled to the same shaft. What is the angular speed of the resultant combination of the shaft and two wheels? What fraction of the original rotational kinetic energy is lost in the collision?

A 3 kg disk of radius 0.25m is rotating freely at an angular speed of 100 rad/s on a shaft passing through the center of mass of the disk. A 2 kg solid ball of the same radius, initially not rotating, slides down the shaft(the shaft passes through the ball's center of mass) and is coupled to the disk. Assuming that the rotational inertia of the shaft is negligible, a) What is the angular speed of the disk-ball combination, b)...

A bicycle wheel with a radius of 0.40 meters has a mass of 2.25 kg mostly :concentrated near the rim. Treat the wheel as a ring of mass, I_ring = m r^2, rotating at 146 rpm (15.3 rad/s). Brakes on the rim slow the wheel to a stop at a constant angu acceleration. the angular acceleration, a, of the wheel if it is brought to rest in 5 seconds is the moment of inertia of the wheel, I, is closest...

A child pushes her friend (m = 25 kg) located at a radius r = 1.5 m on a merry-go-round (rmgr = 2.0 m, Imgr = 1000 kg*m2) with a constant force F = 90 N applied tangentially to the edge of the merry-go-round (i.e., the force is perpendicular to the radius). The merry-go-round resists spinning with a frictional force of f = 10 N acting at a radius of 1 m and a frictional torque τ = 15 N*m...

A handbrake is applied to a rotating wheel, initially moving counterclockwise, causing it to slow down with a constant angular acceleration of magnitude 5.20 rad/s2. Immediately after the handbrake is applied, the wheel rotates through 57.9 rad during a 4.00 s time interval. What is the angular speed (in rad/s) of the wheel at the end of this time interval?

6. (BONUS) Two particles each with mass m = 0.4 kg, are fastened to each other, and to a rotation axis at 0, by the two thin rods, each of length d and mass M = 1.5 kg as shown below. The combination rotates around the rotation axis with angular speed w = 0.2 rad/s. The total moment of inertia of the system measured about O is 2.3 x 10-4 kg m?. (Hint: The moment of inertia of a thin...

A uniform cylindrical turntable of radius 1.80 m and mass 25.0 kg rotates counterclockwise in a horizontal plane with an initial angular speed of 4T rad/s. The fixed turntable bearing is frictionless. A lump of clay of mass 2.28 kg and negligible size is dropped onto the turntable from a small distance above it and immediately sticks to the turntable at a point 1.70 m to the east of the axis. (a) Find the final angular speed of the clay...
