A body of mass 1 kg breaks due to an explosion into three pieces of mass ratio `1:1:3` . Two equal masses move at right angles to each other , and attain a velocity `30 m*s^(-1)`. What is the velocity of the heavier piece ?

Text Solution

Verified by Experts

The correct Answer is:
`10 sqrt(2) m*s^(-1)` at `135^@` with the direction of the velocities of other two pieces
