Coefficient of restitution during the collision is changed to 1/2 keep

1.	Coefficient of restitution during the collision is changed to 1/2 keepting all other parameters unchanged. What is the velocity of the ball B after the collision ?
Answer» `(1)/(2)(3sqrt(3)hat(i) + 9hat(J)) m//s` `(1)/(4)(9hat(i) - 3sqrt(3)hat(j)) m//s` `(6HAT(i) + 3sqrt(3)hat(j))m//s` `(6hat(i) - 3sqrt(3)hat(j))m//s` ANSWER :B
