A ball A$,$ mA$=2\mathrm{.}3[$kg$],$ is falling vertically with a velocity vA$1=5[$m$/$s$]$ when it is hit by a ball B$,$

mB$=1\mathrm{.}4[$kg$],$ which has velocity vB$1=5[$m$/$s$].$ The coefficient of restitution between the two balls is

e$=0\mathrm{.}8.$ Assume there is no friction between the balls during the impact. Angle $=30$o$.$

Q$8$: Determine the magnitude of velocity of ball A$,$ vA$2[$m$/$s$],$ immediately after the impact.

Q$9$: Determine the magnitude of velocity of ball B$,$ vB$2[$m$/$s$],$ immediately after the impact?
