Add The issue of the character dragging on the ground with Add Impulse.

Hello everyone,
I’m developing a solo FPS combat game. When my character dies, I apply an add impulse, making sure it acts from the direction of the bullet’s trajectory.

I apply this when my character falls to the ground and dies. I like how it works. However, when I fire in rapid succession, my character gets dragged along the ground. How can I stop this?

Thanks.
