A solid cylinder of mass 3.1 kg and radius 6.3 cm rolls down an inclined plane of height 4.7 cm without slipping, then the speed of its center of mass when the cylinder reaches the bottom in (m/s): (Hint: The following pictures depict the moments of inertia of a solid cylinder about two different axes and the corresponding formula. You can use the appropriate formula to solve the above question) Axis Axis Solid cylinder (or disk) about central axis Solid cylinder (or disk) about central diameter

The uniform solid block in the figure has mass 25.9 kg and edge lengths a = 0.763 m, b-1.40 m, and c=0.114 m. Calculate its rotational inertia about an axis through one corner and perpendicular to the large faces. Rotation asis Number Units

The outstretched hands and arms of a figure skater preparing for a spin can be considered a slender rod pivoting about an axis through its center (Figure 1). When his hands and arms are brought in and wrapped around his body to execute the spin, the hands and arms can be considered a thin-walled hollow cylinder. His hands and arms have a combined mass 8.0 kg. When outstretched, they span 1.6 m ; when wrapped, they form a thin-walled hollow cylinder of radius 26 cm. The moment of inertia about the rotation axis of the remainder of his body is constant and equal to 0.4 kg⋅m2. If his original angular speed is 0.30 rev/s, what is his final angular speed?

Please help: Find the moment of inertia of the wheel if the block rises to a height of h=6.9 cm before momentarily coming to rest. Express answer with two significant figures
