Question

Identify whether the following describe distance (d), velocity (v), or acceleration (a).

1. 5.2 meters per second squared (m/s²)
2. Omar moves 5 m to the couch from the kitchen.
3. It takes Omar 3 seconds to move 5 m.
4. A car is traveling at 6.7 m/s.
5. The car slows from 6.7 m/s to 0 m/s over 7 seconds.
- a) (a, d, t, v, a)
- b) (d, d, t, v, a)
- c) (a, v, t, v, d)
- d) (v, d, t, a, t)

Answer 1

The given scenarios describe acceleration, distance, time, velocity, and acceleration, in that order. The correct answer to the question is a) (a, d, t, v, a). This is determined by analyzing the units and context provided for each scenario.

Step-by-step explanation:

To identify whether each scenario describes distance (d), velocity (v), or acceleration (a), we can refer to their units and definitions.

• 5.2 meters per second squared (m/s²): This unit is associated with acceleration, as acceleration is the rate of change of velocity with respect to time, measured in m/s².
• Omar moves 5 m to the couch from the kitchen: This scenario describes a distance because it indicates a length of 5 meters, with no reference to how long it took him.
• It takes Omar 3 seconds to move 5 m: This information gives us a time (t) rather than a velocity or acceleration since it doesn't provide the rate of change.
• A car is traveling at 6.7 m/s: This is a velocity, as it provides a speed with a certain magnitude and direction.
• The car slows from 6.7 m/s to 0 m/s over 7 seconds: This scenario illustrates acceleration since the velocity of the car is changing over some time.

Therefore, the correct answer is a) (a, d, t, v, a), which corresponds to acceleration, distance, time, velocity, and acceleration, respectively.
