cos(theta) cannot be more than one. Take delta h positive in both the cases.

with this formula i found delta h to be =.017m
delta(h)=l-lcos
l=lenght
and then i plugged that in for mgh=PE
(.065)(9.8)(.017)=.010829
and then i used Ke=1/2m1Vi^2
since this is inelastic the potential equals the kinetic energy right?
