A ball mass 2 kg moving horizontally with velocity 10 m/s hits a wedge of mass 5 kg placed on a horizontal surface as shown in the figure. Just after collision klvelocity of wedge is 3.2 m/s. There is no friction at any contact surface. Then (take sin `30^(@)=3//5`)

A

Speed of ball just collision id `2sqrt10` m/s

B

limpulse applied by ball on the wedge during collsion is 20 N-s
