Question

1. match the description with the speed vs. time graph. a. at rest b. constant speed c. slower acceleration d. deceleration e. faster acceleration

Explanation:

1. At rest means speed is 0, which is shown at the start - speed is 0.
2. Constant speed is a horizontal line on speed - time graph as speed doesn't change with time.
3. Slower acceleration has a less - steep positive slope on the graph.
4. Deceleration has a negative slope on the graph.
5. Faster acceleration has a steeper positive slope on the graph.

Answer:

1. A. At rest: Speed is 0 at the start of the motion.
2. B. Constant speed: A horizontal line on the speed - time graph.
3. C. Slower acceleration: A less - steep upward - sloping line.
4. D. Deceleration: A downward - sloping line.
5. E. Faster acceleration: A steeper upward - sloping line.
