medium · Enhanced ACT science
In an experiment, a cart was released from rest at the top of a ramp and its speed was measured at fixed distances down the ramp:
| Distance (m) | Speed (m/s) |
| :--- | :--- |
| 0.5 | 1.4 |
| 1.0 | 2.0 |
| 1.5 | 2.4 |
| 2.0 | 2.8 |
Which statement best describes the relationship between distance traveled and the cart's speed?
- As distance increases, speed decreases steadily.
- As distance increases, speed increases, but by smaller amounts for each added 0.5 m.
- Speed stays constant as distance increases.
- Speed increases by the same amount for each added 0.5 m of distance.
