A car traveling in a straight line has a velocity of 6.64 m/s at some instant. After 5.55s, its velocity is 10.9 m/s.
What is its average acceleration in this time interval?
Answer in units of m/s
To find the average acceleration, we need to use the equation:
Average acceleration = (Change in velocity) / (Change in time)
Given that the initial velocity (u) is 6.64 m/s and the final velocity (v) is 10.9 m/s, the change in velocity is:
Change in velocity = v - u = 10.9 m/s - 6.64 m/s = 4.26 m/s
And the change in time is:
Change in time = 5.55 s
Now we can calculate the average acceleration:
Average acceleration = (Change in velocity) / (Change in time)
= 4.26 m/s / 5.55 s
≈ 0.768 m/s²
Therefore, the average acceleration of the car in this time interval is approximately 0.768 m/s².
