A light rigid rod 1.00 m in length rotates about an axis perpendicular to its length and through its center as shown below. Two particles of masses 4.00 kg and 3.00 kg are connected to the ends of the rod. What is the angular momentum of the system if the speed of each particle is 6.60 m/s? J-s 1.00

A 10 kg wheel with a 0.4 meter radius is rotating at 4 rad/s. A 8 Nm torque is applied to the wheel. The rotational inertia of the wheel is 0.48 kgm2. The angular momentum of the wheel changes by 4 kg*m2/s. How long was the torque applied to the wheel.   - 8 s - 3 s - 4 s  - 0.5 s

A 0.02 kg mass red object (bead) is moving at a speed of 10.0 m/s when it sticks to the edge of a uniform solid cylinder. The cylinder is free to rotate about its axis through its center and has a mass of 0.5 kg , a radius of 0.25 m and is initially at rest. I = 1/2MR​2^2 a) What is the angular velocity of the system after the collision? b) How much kinetic energy is lost in the collision? c) If the angular position of the Cylinder varies as θ(t)=3.2t-t​^2 ​find the centripetal acceleration of the red object (bead). d) A cord is now wrapped around the cylinder. Use the work energy theorem to find the angular velocity of the cylinder after 5.0m of cord have been removed by a 40N Force. e) If the 40N force on the cord is replaced by a 40-N weight, what is the angular velocity of the cylinder after 5.0m of cord has unwound?

As shown in Figure , a 0.500 kg stone moving horizontally with a speed of 2.25 m/s collides with a 0.750 m long stationary vertical uniform rod. The rod has a mass of 1.50 kg and is fixed to the ground by a frictionless hinge. After the collision, the stone drops vertically down to the ground. What is the angular speed of the rod just after the collision? 0.25 m A) 2.00 rad/s B) 1.00 rad/s C) 3.00 rad/s D) 4.00 rad/s E) 5.00 rad/s stone v = 2.25 m/s 0.75 m Hinge
