v=squareroot((kx^2)/(m1+m2) m1v1=(m1+m2)v m1v1=(m1+m2)squareroot((kx^2)/(m1+m2) m1^2v1^2=m1+m2((kx^2)/(m1+m2)) then the m1+m2 cancel iam sorry i not getting this i just can't see where iam going wrong Or did you mean m1v1=(m1+m2)v v=m1v1/(m1+m2) & v=squareroot((kx^2)/(m1+m2) so...

yes the bullet sticks to the block and i am trying to figure out what m2 is so I am not sure how to incorporate ½(m1 + m2)v² (instead of ½m1v²).

Homework Statement a bullet of mass 0.005kg traveling at 120m/s hits a block at rest that falls and compresses a spring (k=99n/m) to a maximum compression of 0.121m what is the mass of the block? (solve using momentum) m1=0.005kg m2=? v1=120m/s v`=? k=99n/m x=0.121m Homework Equations...
