c)When A throws the ball ,then applying LCLM
44*(10/11) = 4*5+40*v
v= 3/2 m/s(towards left)
When B recieves the ball ,applying LCLM
40*1+4*5=44*v ( towards right)
v = 60/44 m/s
When B throws the ball , then applying LCLM
v= (44/44)=1 m/s (towards right)
When A catches the ball ,then appltuing LCLM
-4*5 + 40(3/2) = - 44 v v= - 10/11 m/s v = 10/11 m/s (towards left)
similarly after 5 round trips
the velocity of A will be(50/11) m/s and velocity of B will be 5 m/s
