Which of the following graph shows the variation of velocity with mass for the constant momentum?
For constant momentum, we know that the momentum \( p \) is given by the equation: \[ p = mv, \] where \( m \) is the mass and \( v \) is the velocity. For constant momentum, we can rearrange the equation to get: \[ v = \frac{p}{m}. \] This shows that velocity \( v \) is inversely proportional to mass \( m \), meaning as the mass increases, the velocity decreases, and vice versa.
The graph that shows this inverse relationship is a hyperbola, which corresponds to Fig 1.
Thus, the correct graph is Fig 1.
A solid cylinder of mass 2 kg and radius 0.2 m is rotating about its own axis without friction with angular velocity 5 rad/s. A particle of mass 1 kg moving with a velocity of 5 m/s strikes the cylinder and sticks to it as shown in figure.
The angular velocity of the system after the particle sticks to it will be:
