A bullet fired with speed u sticks to the block after penetrating some distance 'X' inside the block after that both move together with same velocity, if average force of resistance on bullet by block was P, 'S' is distance moved by bullet during time of collision. 'y' is distance moved by block in duration of collision.

(1 → q) ; (2 → p) ; (3 → r) ; (4 → s)
Los in kinetic energy = maximum possible heat generated
= 
u 2
mu = (M + m) V ⇒ V = 
= a
= u 2 – 
S
S = 
u 2 m
Work done by bullet ion clock = Py
y = 
= u – Pt ⇒ Pt = u – 
t = 
y = 
y =
