# For a constant force, suppose the duration of impact on an object is doubled. How much is the impulse increased? How much is the resulting change in momentum increased?

Both are doubled.

#### Explanation:

Impulse is force*time. Also, impulse is change in momentum. Therefore,
$\text{force*time" = "change in momentum}$

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,
