355316 A body of mass \(5 \times {10^3}\;kg\) moving with speed \(2\;m{s^{ - 1}}\) collides with a body of mass \(15 \times {10^3}\;kg\) inelastically and sticks to it. Then, loss in kinetic energy of the system will be

1 \(7.5\,kJ\)
2 \(15\,kJ\)
3 \(10\,kJ\)
4 \(5\,kJ\)

355317 During inelastic collision of two bodies:

1 \(K E_{\text {final }}\) must be greater than \(K E_{\text {initial }}\)
2 \(K E_{\text {final }}=K E_{\text {initial }}\)
3 \(K E_{\text {initial }}\) may be greater or less than \(K E_{\text {initial }}\)
4 \(K E_{\text {final }}\) must be less than \(K E_{\text {initial }}\)

355318 Three blocks \(A, B\) and \(C\) are lying on a smooth horizontal surface, as shown in the figure. \(A\) and \(B\) have equal masses \(m\), while \(C\) has mass \(M\). Block \(A\) is given an initial speed \(v\) towards \(B\) due to which it collides with \(B\) perfectly inelastically. The combined mass collides with \(C\), also perfectly inelastically \(\dfrac{5^{\text {th }}}{6}\) of the initial kinetic energy is lost in whole process. What is value of \(M / m\) ?
