12. Bicycle Wheel. A simple bicycle wheel composed of a tire of mass 2.00 kg and radius 0.600 m and12 radial spokes each of mass 0.100 kg is lain flat on the ground and allowed to spin about its center suchthat the tire is moving at v = 5.00 m/s. A rock of mass 0.800 kg moving at 3.00 m/s hits one of spokesperpendicularly and at a distance of 0.200 m away from the center, as shown in the figure. If the rock sticksto the spoke and the wheel continues to rotate about its center, find the resultant angular velocity of thewheel-rock combination.

we will use the law of conservation of angular momentum to get the final angular velocity

Concept explainers

Moment of Inertia

Inertia can be termed as a resistance offered by a body to change its state. A rigid body initially at rest will apply resistance when acted by an external force that tends to change its state of rest or velocity, or a body initially at motion will provide resistance in changing its state of velocity or motion for coming to a state of rest. In other words, Newton's first law of motion describes the law of inertia of a rigid body.

Question

12. Bicycle Wheel. A simple bicycle wheel composed of a tire of mass 2.00 kg and radius 0.600 m and
12 radial spokes each of mass 0.100 kg is lain flat on the ground and allowed to spin about its center such
that the tire is moving at v = 5.00 m/s. A rock of mass 0.800 kg moving at 3.00 m/s hits one of spokes
perpendicularly and at a distance of 0.200 m away from the center, as shown in the figure. If the rock sticks
to the spoke and the wheel continues to rotate about its center, find the resultant angular velocity of the
wheel-rock combination.

A wheel is attached by a cable to a block The wheel has a radius of 2ft and weighs 300lbs, the block weights 20lbs. If the radius of gyration about the point of rotation of the disk is 1.5ft, how many revolutions will it take for the wheel to come to a stop assuming it was moving at 10 rad/s CW. Assume the block is on the left side of the wheel and thus causes a CCW moment.
Dynamics Lesson:I want detailed and manual solution.
A drum can rotate about a fixed-point O. The A block is attached to a cord wrapping around the drum. The mass of the drum is md = 100kg and the radius is r = 0.5 m. The radius of gyration of the drum about point O is ko=0.3 m. The mass of the block is mb= 20kg. The block is released from rest. The acceleration due to gravity is g=9.81 m/s2. (1) Calculate the mass moment of inertia of the drum about the point O, IO_______(kgm2) (two decimal places)
