Answer 1

I et or the balls. o= angle after collision between hit y = common velouty after stick. conserve the momentum calouge, +Ride = (b + Posbe m, vi cosø + mVei cosp.) = (m, + m) V cosa tie mage (Yep_cos que + Voi Lordsy) = 2013 (xcese) (i cosa + 2y coso 1 - 2 v coso to Vi= 2V77 and D = 0,=66) 3 Vi coso = 2y coso
