Of a rope wrapped around a pulley chain
Its either releasing a stretch rubber band and a ball rolling down a hill because rubber have a potential to move when its stretch and its an eleastic potential energy also a ball rolling down a hill is a gravitational to kinetic energy because the ball started at rest which is art the top of the hill and it has a potential to fall. Once its started rolling its energy transfer into kinetic energy.
Hope this helps

Answer:
Average Velocity = - 1.22 cm/s = - 0.0122 m/s
Explanation:
The average velocity of an object is defined as the ratio of the total distance traveled by the object to the total time taken by the object to cover the distance. Therefore, the average velocity of an object can be found by the following formula:
Average Velocity = Total Distance Covered/Total Time Taken
Average Velocity = (Final Position - Initial Position)/Total Time Taken
Average Velocity = (3.7 cm - 6.5 cm)/(2.3 s)
Average Velocity = (- 2.8 cm)/(2.3 s)
<u>Average Velocity = - 1.22 cm/s = - 0.0122 m/s</u>
here, the negative sign indicates the direction of the velocity or the movement of the object is leftwards or towards the origin approaching from right.
