Question

A body of mass 1 kg moving with an initial velocity u hits another body of mass m2 which is at rest after collision of velocity of the first body becomes ine fourth of initial u then what is the value of mass m2

Answer 1

->>

The ratio of K.E of colliding body before and after collision ... Being head on elastic collision how the mass will add ... K E of colliding bodies before collision =12mv2.

Answer 2

Explanation:

The ratio of K.E of colliding body before and after collision ... Being head on elastic collision how the mass will add ... K E of colliding bodies before collision =12mv2.
