COLLISIONS
Work, Energy and Power

268622 About a collision which is not correct

1 physical contact is must
2 colliding particles can change their direction of motion
3 the effect of the external force is not considered
4 linear momentum is conserved
Work, Energy and Power

268623 In one-dimensional elastic collision, the relative velocity of approach before collision is equal to

1 relative velocity of separation after collision
2 'e' times relative velocity of separation after collision
3 \(1 / e^{\prime}\) ' times relative velocity of separation after collision
4 sum of the velocities after collision
Work, Energy and Power

268624 Two identical bodies moving in opposite direction with same speed, collide with each other. If the collision is perfectly elastic then

1 after the collision both comes to rest
2 after the collision first comes to rest and second moves in the opposite direction with same speed.
3 after collision they recoil with same speed
4 both and 1 and 2

268625 A body of mass ' \(m\) ' moving with certain velocity collides with another identical body at rest. If the collision is perfectly elastic and after the collision both the bodies moves

1 in the same direction
2 in opposite direction
3 in perpendicular direction
4 at \(45^{\circ}\) to each other
