A particle of mass M is at rest when it suddenly explodes into there picces of equal massses. One piece flies out along the positive x-axis with a speed of `30`m/s while anotheer goes in the negative y direction with a speed of `20`m/s
Find the componenrts of the cvelocity of the third piece.
Repeat if the third piecre has a mass `M//2` and the other two each have mass `M//4`

Text Solution

Verified by Experts

The correct Answer is:
`"["-30m//s.20m//s,-10m//s"]"`
