Impulse # 2
A system of two blocks A and B are connected by an inextensible massless string as shown in above figure. The pulley is massless and frictionless . Initially , the system is at rest .
A bullet of mass moving with a velocity as shown above hits block B and gets embedded into it . The impulse imparted by tension force to the block A is ?

By conservation of Linear momentum along the string ,
m u = ( m + m + 3 m ) v ⟹ v = 5 u ( v is the common instantaneous velocity just after the collison )
Therefore the impulse on block A = I = 3 m ( v − 0 ) = 5 3 m u
