Final answer:
To calculate the average velocity of the top of the ladder on each time interval, divide the change in position by the change in time.
Step-by-step explanation:
The average velocity of the top of the ladder on each of the given time intervals can be found by dividing the change in position by the change in time. The formula for average velocity is:
average velocity = (final position - initial position) / (final time - initial time)
Let's say the ladder is initially at position x1 at time t1, and finally at position x2 at time t2. Then, the average velocity during this time interval is:
average velocity = (x2 - x1) / (t2 - t1)
Repeat the above calculation for each time interval and you will find the average velocity of the top of the ladder on each interval.
