Two spheres A and B, of equal radii, lie at rest on a smooth horizontal table. Sphere A has mass 2m kg and sphere B has mass 16m kg. Sphere A is projected with speed 3 ms–1 towards sphere Band...
By def of coefficient of restitution say `mu`
`mu=v/u` v is the velocity after collision and u is velocity before collision.
`v=1.5ms^(-1)` in the same direction in which sphere was projected.
Since impulse is defined as rate of change of momentum,therefore
