2D Collision Example
A ball collides elastically with another ball of the same mass. The collision is oblique and initially second ball was at rest. After the collision, the two balls move with same speeds. What will be the angle between the velocities of the balls after the collision?
- Less than
- More than
- All the above choices are correct.
- The magnitude of the momentum of the composite body is
- The composite body moves in a direction making a angle with the x-axis.
- The loss of kinetic energy as a result of collision is
- 2.54 i + 1.62 j
- 2.54 i - 1.62 j
- 1.89 i + 0.83 j
- 1.89 i - 0.83 j
Two equal spheres of mass m are in contact on a smooth horizontal table. A third identical sphere impinges symmetrically on them and is reduced to rest. Find the loss of K.E
