No starting velocity was given, so I can't give a correct answer, but I can answer part of the question. Given an acceleration and a time through which an object accelerates, you can determine the change in velocity. Acceleration is just the change of velocity over a period of time. Since we have an acceleration of -3.1 meters per second squared, acting for two seconds, we have a change in velocity of -6.2 meters per second. Take the original velocity and subtract 6.2 meters per second to get the answer.

In general, the acceleration during that time interval could vary considerably. However, we can calculate the average acceleration during the interval. The change in speed is 20 meters per second - 5 meters per second = 15 meters per second, and this change in speed occurs over a 3 second interval. Thus the average change in speed over this interval is 15 meters per second/ 3 seconds = 5 meters per second per second = 5 meters/second2
Seconds are not squared in the acceleration formula. The units for acceleration are meters per second squared (m/s^2), where the time unit (seconds) is squared to represent the change in velocity over time.

Acceleration measures the rate of change of velocity over time. The squared seconds unit is used because acceleration is the change in velocity per unit time, so it is expressed as distance per time squared. This allows us to quantify how quickly the velocity of an object is changing over time.
Acceleration occurs when velocity changes over time. The formula for it is as follows: a = (Vf - Vi) / t a: acceleration (meters/seconds2) Vf: Final velocity (meters/seconds) Vi: Initial Velocity (meters/seconds) t: Time (seconds)
The SI unit for acceleration is meters per second squared (m/s^2). This unit represents how the velocity of an object changes over time.
The phrase "ten meters per second squared" describes the acceleration of an object experiencing a change in velocity at a rate of 10 meters per second each second. It represents how quickly the object's speed is increasing over time.
Acceleration is the rate of change of velocity over time. By dividing a unit of velocity by a unit of time, we can derive the unit of acceleration. For example, if velocity is measured in meters per second (m/s) and time is measured in seconds (s), acceleration would be in meters per second squared (m/s^2).
To find out how many meters the yellow jacket can fly in a minute, you would first calculate its speed over 9 seconds: 4.5 meters รท 9 seconds = 0.5 meters per second. Then, to find out how many meters per minute, you would multiply by 60 (since there are 60 seconds in a minute): 0.5 meters/second x 60 seconds = 30 meters per minute.
The SI unit of negative acceleration is meters per second squared (m/s^2). This unit represents the decrease in velocity over time.
