An object with negative acceleration whose acceleration points the same way as its motion is:
ASlowing down steadily
BHeld at constant speed
CMomentarily at rest
DSpeeding up steadily
Answer & Solution
Correct answer: D. Speeding up steadily
1. The sign of acceleration depends on the coordinate system chosen.
2. Whether an object speeds up depends only on whether acceleration and velocity point the same way.
3. Because its acceleration is in the same direction as its motion, it is speeding up, not decelerating.
4. A negative sign here just means both vectors point toward the left.
5. Reading the sign as slowing down is the classic error this distinction guards against.
