A body of mass `1kg` initially at rest explodes and breaks into threee fragments of masses in the ratio `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 ? .

Text Solution

Verified by Experts

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