365824 A body just dropped from a tower explodes into two pieces of equal mass in mid-air. Which of the following is not possible?

1 One part reaches the ground earlier then the other
2 Each part will follow parabolic path
3 Only one part will follow parabolic path
4 Both parts move along a vertical line

365825 A bomb at rest explodes into 3 parts of same mass. The momentum of two parts is \(-3 p \hat{i}\) and \(2 p \hat{j}\) respectively. The magnitude of momentum of the third part is

1 \(p\)
2 \(\sqrt{5} p\)
3 \(\sqrt{11} p\)
4 \(\sqrt{13} p\)

365826 An isolated particle of mass \(m\) is moving in a horizontal \((x-y)\) plane along the \(x\)-axis, at a certain height above the ground. It suddenly explodes into two fragements of masses \(\frac{m}{4}{\rm{ }}\& \,\frac{{3m}}{4}\). An instant later, the smaller fragment is at \(y = + 15\;cm\). The larger fragment at this instant is at (Assume \(g = 0\) )

1 \(y = - 20\;cm\)
2 \(y = - 5\;cm\)
3 \(y = + 5\;cm\)
4 \(y = + 20\;cm\)

365827 A body falling vertically downwards under the gravity breaks in two parts of unequal masses. The centre of mass of the two parts taken together shifts horizontally towards

1 Heavier piece
2 Lighter piece
3 Does not shift horizontally
4 Depends on the vertical velocity at the time of breaking
