Doubling the kinetic energy of an object does what to momentum?

Would doubling the kinetic energy of an object have any effect on the momentum?

Yes, KE=p^2/2m.

Yes,According to this equation showing the relation between momentum and kinetic energy:
[Latex]E_k = \frac {p^2}{2m}[/Latex]
I tried reversing the equation and I think you should a negative effect on the momentum

What do you mean by negative effect? If the kinetic energy increases the momentum increases (although it won't double).

Im stuck on this.

How could a nest of insects have a momentum of zero?

Diogenes, momentum is a vector. All the insects momentum vectors could add up to nothing.
