Momentum and CollisionHard
Question
A system of two blocks A and B are connected by an inextensible mass less strings as shown. The pulley is mass less 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 ended into it. The impulse imparted by tension fore to the block of mass 3m is -
Options
A.
B.
C.
D.
Solution
- Nᐃt = m(v - u) ; Nᐃt - Tᐃt = m(v - 0)
Tᐃt = 3m (v - 0) ⇒ v = u / 5
∴ Impulsive tension T =
