A particle of mass m moving with speed u collides perfectly inelastically with another particle of mass 3 m at rest. Loss of KE of system in the collision is

A particle of mass m moving with speed u collides perfectly inelastically with another particle of mass 3 m at rest. Loss of KE of system in the collision is

Two bodies of equal masses moving mutually at right angles to each other, collide elastically. After the collision, the particles will move in

A particle of mass m moving with velocity u collides elastically with a particle of mass 3m at rest. After collision the heavier particle moves with velocity.

A particle A of mass m and initial velocity v collides with a particle of mass m//2 which is at rest. The collision is head on, and elastic. The ratio of the de-broglie wavelength lambda_(A) and lambda_(B) after the collision is
