Question

a bomb of mass 10kg is initially at rest explodes into two parts.Mass of 4kg is moving with kinetic energy of 200J.Velocity of other mas is​

Answer 1

Explanation:

Total mass is 10 kg

K=1/2mv²

200=4×v²

v²=200/4=50

v=root50

So,

Mass other one is 6 kg

And according to law of conservation of linear momentum

Velocity will be same of the bomb pieces.
