a car traveling in a straight line has a velcoity of 2.43 m/s at some instant. After 6.73 s, its velocity is 9.81 m/s. what is its average acceleration in this time interval?

To find the average acceleration of the car during the given time interval, we need to use the formula:

Average acceleration = (Change in velocity) / (Change in time)

First, we need to calculate the change in velocity:
Change in velocity = Final velocity - Initial velocity

Given that the initial velocity is 2.43 m/s and the final velocity is 9.81 m/s, we can calculate the change in velocity:
Change in velocity = 9.81 m/s - 2.43 m/s = 7.38 m/s

Next, we need to calculate the change in time:
Change in time = Final time - Initial time

Given that the initial time is 0 seconds and the final time is 6.73 seconds, we can calculate the change in time:
Change in time = 6.73 s - 0 s = 6.73 s

Now, we can substitute these values into the formula for average acceleration:
Average acceleration = (Change in velocity) / (Change in time)
Average acceleration = 7.38 m/s / 6.73 s

Calculating this division, we find that the average acceleration of the car during the given time interval is approximately 1.096 m/s².
