The moment of inertia of a rigid body about an axis

Seven identical discs are arranged in a planar pattern, so as to touch each other as shown in the figure. Each disc has mass $$m$$ radius $$R$$. What ...

The angular speed of a motor wheel is increased from $$1200 \mathrm{~rpm}$$ to $$3120 \mathrm{~rpm}$$ in $$16 \mathrm{~s}$$. The angular acceleration ...

In figure $$E$$ and $$v_{\mathrm{cm}}$$ represent the total energy and speed of centre of mass of an object of mass $$1 \mathrm{~kg}$$ in pure rolling...

A wheel starting from rest gains an angular velocity of $$10 \mathrm{~rad} / \mathrm{s}$$ after uniformly accelerated for $$5 \mathrm{~s}$$. The total...

A thin uniform rectangular plate of mass $$2 \mathrm{~kg}$$ is placed in $$x y$$-plane as shown in figure. The moment of inertial about $$x$$-axis is ...

A particle is moving uniformly along a straight line as shown in the figure. During the motion of the particle from $$A$$ to $$B$$, the angular moment...
