Question
A system of two blocks A and B are connected by an inextensible massless strings as shown. The pulley is massless and frictionless. Initially the system is at rest when, a bullet of mass ′m′ moving with a velocity ′u′ as shown hits the block ′B′ and gets embedded into it. The impulse imparted by tension force to the block of mass 3m is :
Options
A.
B.
C.
D.
Solution
use momentum conservation equation
m.u. = 5mv
V =
Impulse imparted by tension force to block of mass 3m.
= 3mx v =
