very urgent sir, pls try to solve it within 20 mins. I dont have much more information.
Transcribed Image Text:In a game of billiards, ball A is given an initial
velocity Vo along the longitudinal axis of the table.
It hits ball B and then ball C, which are both at rest.
Balls A and C are observed to hit the sides of the
table squarely at A' and C, respectively, and ball B
is observed to hit
the side obliquely at B'. Knowing that Vo = 5.69
m/s, Vc = 3.69 m/s, and c = 1.8 m, determine (a)
the velocities Va and Vb of balls B and C, (b) the
point A' where ball A hits the side of the table.
Assume frictionless surfaces and perfectly elastic
impacts (i.e., conservation of energy).
