Mblock=.992kg K=.650/.003=216.7 N/mstart by finding the velocity of the bullet block system withconservation of energy. .5kx^2=.5mv^2
v=sqrt(k*x^2)/m
v=2.21m/s
Now find the the velocity of the bullet with conservation ofmomentum
mbulletVbullet+mblockVblock=(m+m)v
mV+0=(m+m)v
V=((m+m)*v)/m
V= ((.992+.008)*2.21)/.008
V=276 m/s
