Terminator 3: Rise of the Machines

At that moment Terminator fired the first 40mm grenade, hitting T-X squarely in
the chest with a tremendous explosion that shoved her back several steps, almost
off her feet.

But she recovered, and had taken a step forward when Terminator fired a second
grenade at her, which hit her chest again, shoving her backward.

Not waiting for her to recover, Terminator fired again as he moved toward her.
Each time she was pushed back several feet by the force of the blast. And each
time before she could regain her forward momentum from the attack, Terminator
fired again.

With the last grenade T-X was pushed back into the broad louvers over the main
ventilation shaft that shattered from her weight. She disappeared through the
opening.
