$2001$B$2.$ An incident ball A of mass $0\mathrm{.}10$ lg is sliding at $1\mathrm{.}4$ m$\text{'}$s on the horizontal tabletop of negligible friction asshown above. It males a head on collision with a target ball B of mass $0\mathrm{.}50$ kg at rest at the edge of the table. As a result of the collision, the incident ball rebounds, sliding backwards at $0\mathrm{.}70$ m$/$s immediately after the collision aj Calculate the speed of the $0\mathrm{.}50$ kg target ball immediately after the collisionThe tabletop is $1\mathrm{.}20$ m above a level, horizontal floar. The target ball is projeted horizontally and intially strikes the floor at a horizontal displacement d from the point of collisionb. Calculate the horizontal displacementIn another experiment on the same table, the target ball B is replaced by target ball C of mass $0\mathrm{.}10$ kg$.$ The incident ball A again slides at $1\mathrm{.}4$ m$\text{'}$s$,$ as shonn below left, but this time makes a glancing collicion with the target ball C that is at rest at the edge of the table. The target ball C strikes the floor at point P$,$ which is at a horizontal displacement of $0\mathrm{.}15$ m from the point of the collicion, and at a horizontal angle of $30\backslash$deg from the x$-$axis as shown below right Calculate the speed of v of the target ball c immediately after the collision.Calculate the y component of incident ball As momentum immediately after the collision
