Question

A body of mass `1kg` initially at rest explodes and breaks into threee fragments of masses in the ration breaks into three fragments of masses in the ration `1: 1: 3`. The two pieces of equal masses fly off perpendicular to each other with a speed of `30m//s` each What is the velocity of heavier fragments ? .

Answer 1

Correct Answer - `10 sqrt2 ms^(-1)` at `45^(@)`
`COLM rArr 3mv = 30 sqrt2m rArr v = 10 sqrt2 m//s`
