A body of mass m1 collides head on perfectly elastically with a stationary body of mass `m_(2)`. If velocities of `m_(1)` before and after the collision are v and –v/3 respectively then the value of `m_(1)//m_(2)` is-

A body of mass m_(1) collides elastically with another body of mass m_(2) at rest. If the velocity of m_(1) after collision is (2)/(3) times its initial velocity, the ratio of their masses is :

A body of mass m_(1) collides elastically with another body of mass m_(2) at rest. If the velocity of m_(1) after collision is (2)/(3) times its initial velocity, the ratio of their masses is :

A ball of mass m_(1) is moving with velocity 3v. It collides head on elastically with a stationary ball of mass m_(2) . The velocity of both the balls become v after collision. Then the value of the ratio (m_(2))/( m_(1)) is

A ball of mass m_(1) is moving with velocity 3v. It collides head on elastically with a stationary ball of mass m_(2) . The velocity of both the balls become v after collision. Then the value of the ratio (m_(2))/( m_(1)) is

A body of mass m_(1) collides elastically with a stationary body of mass m_(2) and returns along the same line with one fourth of its initial speed, then m_(1)//m_(2)=

A body of mass m_(1) collides elastically with a stationary body of mass m_(2) and returns along the same line with one fourth of its initial speed, then m_(1)//m_(2)=

A body of mass m_(1) is moving with a velocity V. it collides with another stationary body of mass m_(2) . They get embedded. At the point of collision, the velocity of the system.
