What is the total momentum of the system of particle ?
Two hollow spheres each of mass $M$ and radius $\frac {R}{2}$ are connected with a massless rod of length $2R$ as shown in figure. What will be the moment of inhertia of the system about an axis $yy'$ passing through the center of one of the sphere and perpendicular to the rod
$A$ block of mass $m$ is attached to a pulley disc of equal mass $m$, radius $r$ by means of a slack string as shown. The pulley is hinged about its centre on a horizontal table and the block is projected with an initial velocity of $5\, m/s$. Its velocity when the string becomes taut will be
A sphere is rotating about a diameter
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 $m / s ^{2}$)
