A snowflake is descending through the sky on a calm day. Its weight acts vertically downwards, while air resistance acts vertically upwards. During the fall, the air resistance rises until it matches the weight, so there is no resultant force acting on the snowflake. Once the two forces are equal, which statement is correct?
- AThe snowflake accelerates.
- BThe snowflake decelerates.
- CThe snowflake is stationary.
- DThe snowflake moves at a constant velocity.
