A uniform cylinder of radius 10 cm and mass 20 kg is mounted so as to rotate freely about a horizontal axis that is parallel to and 5.0 cm from the central longitudinal axis of the cylinder. What is the rotational inertia of the cylinder about the axis of rotation?

When a torque of 32.0 Nm is applied to a certain wheel, the wheel acquires an angular acceleration of 25.0 units. What is the rotational inertia of the wheel?

If a particle has mass of 20 kg moves with an acceleration of \(2.5 \text{ m/s}^2\), then the magnitude of force acting on the particle is (in \(\text{kg}\cdot\text{m/s}^2\)):

The centre of gravity for a solid hemisphere about its diametral base having diameter 120 cm and is symmetric about y-axis is (in cm):

The following are the centroidal coordinates of semicircular plane of \(16\pi\) cm diameter and is symmetric about \(x\)-axis.

The polar moment of inertia of a circular plane of diameter about its centroid is (in \(\text{cm}^4\)):

A ball of mass 0.1 kg, initially at rest, is dropped from height of 1 m. Ball hits the ground and bounces off the ground. Upon impact with the ground, the velocity reduces by 20%. The height (in m) to which the ball will rise is:
