Velocity of a particle of mass 2 kg changes from v → 1 = ( - 2 i ^ - 2 j ^ ) m s - 1 to v → 2 = ( i ^ - j ^ ) m s - 1 after colliding with a plane surface.

The direction of change in momentum makes an angle tan - 1 1 3 with the positive x -axis.

The angle made by the plane surface with the positive x -axis is tan - 1 1 3 .

The direction of change in momentum makes an angle 90 ° + tan - 1 1 3 with the plane surface.

Two masses, $2 m$ and $m$ are connected by an inextensible light string. The string is passing over a light frictionless pulley. The mass $2 m$ is resting on a surface and mass $m$ is hanging in the air as shown in the figure. A particle of mass, $m$ strikes the mass, $m$ from below in case $(i)$ with a velocity $v_{0}$ and in case $(i i)$ strikes mass $m$ with a velocity $v_{0}$ from top and sticks to it.
