A particle of mass \(4M\) kg at rest splits into two particles of mass \(M\) and \(3M.\) The ratio of the kinetic energies of mass \(M\) and \(3M\) would be:
1. | \(3:1\) | 2. | \(1:4\) |
3. | \(1:1\) | 4. | \(1:3\) |
During an inelastic collision between two bodies, which of the following quantities always remain conserved?
1. | total kinetic energy |
2. | total mechanical energy |
3. | total linear momentum |
4. | speed of each body |
1. | \(\frac{\pi}{6}\) | 2. | \(\frac{\pi}{3}\) |
3. | \(\frac{\pi}{2}\) | 4. | \(\frac{2\pi}{3}\) |
