The acceleration of the rocket-powered sled is approximately -175.41 m/sec², indicating deceleration.

The acceleration of the rocket-powered sled can be calculated using the formula:

acceleration = (final velocity - initial velocity) / time

Substituting the given values, we have:

acceleration = (123 m/sec - 444 m/sec) / 1.83 seconds

acceleration = -321 m/sec / 1.83 seconds

acceleration ≈ -175.41 m/sec²

The negative sign indicates that the sled is decelerating.
