Acceleration would quadruple as both contributing factors have been doubled.

Acceleration would double because both mass and net force contribute equally to it.

The acceleration would remain unchanged because doubling both quantities preserves their ratio.

Acceleration would halve due to increased inertia from doubled mass despite increased force.

Both cars continue in the same direction but exchange speeds.

Both cars stop and do not move anymore.

First car stops, second car moves eastward at four times its original speed.

First car travels westward at double its original eastward speed, second car stands still.

The skater with mass $M$ moves twice as fast as the skater with mass $\frac{M}{2}$.

It's impossible to determine without knowing their exact masses.

Both skaters move at equal velocities but in opposite directions.

The skater with mass $M$ moves at half the velocity compared to the skater with mass $\frac{M}{2}$.

It doubles.

It remains the same.

It halves.

It quadruples.

Its velocity remains constant over time.

Its velocity decreases at a constant rate over time.

Its velocity increases at a constant rate over time.

Its velocity increases at an increasing rate over time.

It causes the box to accelerate down the incline at a rate determined by the component of gravity parallel to the surface.

It has no effect since only normal force affects acceleration on an inclined plane.

It decelerates the box since friction is negligible and opposes motion.

It causes a constant velocity as it acts perpendicular to the direction of motion.
