A bomb of mass \(16 \mathrm{~kg}\) explodes into two pieces of masses \(4 \mathrm{~kg}\) and \(12 \mathrm{~kg}\). The velocity of the \(12 \mathrm{~kg}\) mass is \(4 \mathrm{~ms}^{-1}\). The kinetic energy of the second piece is
- A \(144 \mathrm{~J}\)
- B \(192 \mathrm{~J}\)
- C \(96 \mathrm{~J}\)
- D \(288 \mathrm{~J}\)
Answer & Solution
Correct Answer
(D) \(288 \mathrm{~J}\)
Step-by-step Solution
Detailed explanation
The correct option is B \(288 \mathrm{~J}\) Let the velocity and mass of \(4 \mathrm{~kg}\) piece by \(\mathrm{v}_1\) and velocity and mass of \(12 \mathrm{~kg}\) piece be \(\mathrm{v}_2\) and \(\mathrm{m}_2\) Applying conservation of linear momentum…
