What is the average acceleration a between
14 s and 16 s?
To find the average acceleration between two time intervals, you need to know the initial velocity (v1) and final velocity (v2) at those times. The formula for average acceleration (a_avg) is:
a_avg = (v2 - v1) / (t2 - t1)
In this case, the given time intervals are 14 seconds and 16 seconds. However, we don't have the velocities at those specific times. So in order to find the average acceleration, we need additional information, such as the initial and final velocities, within the given time frame.
