A body of mass `m_(1) ` moving with uniform velocity of 40 m/s collides with another mass `m_(2)` at rest and then the two together begin to moe wit h uniform velocity of 30 m/s. the ratio of their masses `(m_(1))/(m_(2))` is

When a body of mass m_(1) moving with uniform velocity 40 ms^(-1) collides with another body of mass m_(2) at rest, then the two together begin to move with uniform velocity of 30 ms^(-1) . The ratio of the masses (i.e., m_(1)//m_(2) ) of the two bodies will be

A body of mass 2 kg moving with uniform velocity of 40 ms^(-1) collides with another body at rest . If two bodies move together with a velocity of 20 ms^(-1) . Find the mass of the other body .

A body of mass m moving with velocity 3km//h collides with a body of mass 2m at rest. Now, the combined mass starts to move with a velocity

A body of mass m moving with velocity 3km//h collides with a body of mass 2m at rest. Now, the combined mass starts to move with a velocity

If a body of mass m_(1) moving with velocity v_(1) collides inelastically with another mass m_(2) at rest then give the expression for loss in the K.E. of the system.
