268617 Two particles of different masses collide head on. Then for the system

1 loss of \(\mathrm{KE}\) is zero, if it was perfect elastic collision
2 If it was perfect inelastic collision, the loss of \(\mathrm{KE}\) of the bodies moving in opposite directions is more than that of the bodies moving in the same direction
3 loss of momentum is zero for both elastic and inelastic collision
4 1, 2 and 3 are correct

268618 A \(2 \mathrm{~kg}\) mass moving on a smooth frictionless surface with a velocity of \(10 \mathrm{~ms}^{-1}\) hits another \(2 \mathrm{~kg}\) mass kept at rest, in a perfect inelastic collision. After collision, if they move together

1 they travel with a velocity of \(5 \mathrm{~ms}^{-1}\) in the same direction
2 they travel with a velocity of \(10 \mathrm{~ms}^{-1}\) in the same direction
3 they travel with a velocity of \(10 \mathrm{~ms}^{-1}\) in opposite direction
4 they travel with a velocity of \(5 \mathrm{~ms}^{-1}\) in opposite direction
