Question

Find the average velocity vavg of the sled during that time interval.

Answer 1

To find the average velocity ( v_{text{avg}} ) of the sled, divide the displacement by the time taken during the interval of interest.

Explanation

The average velocity ( v_{text{avg}} ) of an object is determined by dividing the total displacement by the time interval taken for that displacement. It's crucial to calculate the change in position or displacement of the sled during the given time interval.

Once you have the displacement and the time interval, dividing the displacement by the time yields the average velocity. This value represents the overall rate of change of the sled's position during that specific time frame.

When determining average velocity, it's important to consider the direction of motion along with the magnitude of displacement. A positive value indicates motion in one direction, while a negative value signifies motion in the opposite direction.

Thus, the average velocity provides insight into how the sled's position changes over the given time interval.

Answer 2

The average velocity of the sled during that time interval is 8 meters per second.

Step-by-step explanation:

To find average velocity
`(\(v_{\text{avg}}\))`, divide the total displacement (160 meters) by the total time (20 seconds). The calculation is
`\(v_{\text{avg}} = \frac{160 \, \text{m}}{20 \, \text{s}} = 8 \, \text{m/s}\).` This indicates that, on average, the sled's velocity was 8 meters per second during the given time interval.

Velocity, a vector quantity with magnitude and direction, is represented here solely by its magnitude. The average velocity reflects the rate of change of displacement over time, providing an overall sense of motion during the specified interval. It's important to differentiate between average velocity and instantaneous velocity, where the latter denotes velocity at a specific instant.
