Answer: Straight sloped line on v-t graph.
- A Horizontal line on v-t graph
- B Straight sloped line on v-t graph
- C Curved line on s-t graph starting at origin
- D Circle on v-t graph
Correct answer: B. Straight sloped line on v-t graph
Explanation: Uniform acceleration means velocity changes at constant rate: a straight sloped line on v-t graph.

Projectiles at equal speed: range is maximum at 45°, and complementary angles (30° and 60°) share the same range. Image: Cmglee, CC BY-SA 3.0, via Wikimedia Commons.
