Collisions
PHXI06:WORK ENERGY AND POWER

355320 Two particles of different masses collide head on. Then for the system

1 Loss of \(K.E\) is zero, if it were perfect elastic collision
2 If it were perfect inelastic collision, the loss of \(K.E\) 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

355321 In the figure, pendulum bob on left side is pulled a side to a height \(h\) from its initial position. After it is released it collides with the right pendulum bob at rest, which is of same mass. After the collision, the two bobs stick together and rise to a height.

2 \(\dfrac{1}{4}\)
3 \(\dfrac{2}{3}\)
4 \(\dfrac{3}{4}\)
