A trolley on a level floor is pushed and then released. If no net external force acted, its acceleration would be:
AFalling off
BReversed
CSimply zero
DRising fast
Answer & Solution
Correct answer: C. Simply zero
1. The first law links net force to acceleration directly.
2. No net force means nothing is changing the velocity.
3. The acceleration is therefore simply zero.
