"In pure translation motion velocity of every particle of body at any instant" is what? Equal or unequal ?
Obtain Newton's second law for system of particle and write it.
In rotational motion of a rigid body, all particle move with
For the given figure find the acceleration of $1\, kg$ block if string is massless and mass of the pulley is $2\, kg$ and diameter of puller is $0.2\, m$ (in $m / s ^{2}$)
A solid sphere rotates about a vertical axis on frictionless bearing. A massless cord passes around the equator of sphere, then passes through over a solid cylinder and then is connected to block of mass $M$ as shown in figure. If the system is released from rest then the speed acquired by block after it has fallen through distance $h$ is
Let $\mathop A\limits^ \to $ be a unit vector along the axis of rotation of a purely rotating body and $\mathop B\limits^ \to $ be a unit vector along the velocity of a particle $ P$ of the body away from the axis. The value of $\mathop A\limits^ \to .\mathop B\limits^ \to $ is
