Mass of the bullet is mb=50gm=0.05Kg
Initial velocity of bullet ub=100m/s
Final velocity is vb=0m/s
(1) Initial momentum of bullet pi=mbub=5Kgm/s
(2) Final momentum of bullet pf=mbvb=0.05×0=0
(3) Retardation occurred by the wooden block is
v2−u2=2as
−(100)2=2a(0.02)
a=−250000m/s2
(4) Resistive force
F=ma
=0.05×−250000
=12500N
