If two masses `m_(1)` and `m_(2)` collide, the ratio of change in their respective velocities is proportional to

A moving body with a mass m_(1) strikes a stationary body of mass m_(2) . The masses m_(1) and m_(2) should be in the ratio m_(1)/m_(2) so as to decrease the velocity of the first body 1.5 times assuming a perfectly clastic impact. Then the ratio m_(1)/m_(2) is

Two particles of a rigid body of masses m_(1) and m_(2) are completing one rotation in paths of radius r_(1) and r_(2) respectively in same time. The ratio of their angular velocities is :

Two particles of mass m_(A) and m_(B) and their velocities are V_(A) and V_(B) respectively collides. After collision they interchanges their velocities, then ratio of m_(A)/m_(B) is

Two particles of mass m_(A) and m_(B) and their velocities are V_(A) and V_(B) respectively collides. After collision they interchanges their velocities, then ratio of m_(A)/m_(B) is

A particle of mass M at rest decay's into two particle of masses m_(1) and m_(2) having non zero velocity. The ratio of the de Broglie wavelengths of the masses lambda _(1) // lambda_(2) is

Two bodies of masses m _(1) and m _(2) fall from heights h _(1) and h _(2) respectively. The ratio of their velocities when the hit the ground is
