Both are doubled.

Explanation:

Impulse is force*time. Also, impulse is change in momentum. Therefore,
#"force*time" = "change in momentum"#

If the force is constant while the time of impact is doubled, the impulse is doubled and the resulting change in momentum is doubled.

I hope this helps,
Steve
