If the spring constant of the bungee rope is greater than that of a rubber band, it will have more elastic potential energy. However, if the spring constant of the rubber band is greater than that of the bungee rope, the rubber band will have more elastic potential energy.
<h3>Elastic Potential energy </h3>
Elastic Potential energy is the stored in a elastic string which has been compressed or stretched.
The formula for calculating elastic potential energy is given as:
- Elastic Potential = 1/2 Kx^2
where
- K is the spring constant of elastic material
- x is the distance if compression or stretch
The elastic potential of an elastic material depends on the spring constant and the distance stretched or compressed.
Since the bungee rope and the rubber band are stretched the same distance, their elastic potential energy depends on their spring constant.
Therefore, if spring constant of the bungee rope is greater than that of a rubber band, it will have more elastic potential energy. However, if the spring constant of the rubber band is greater than that of the bungee rope, the rubber band will have more elastic potential energy.

The speed of Nancy who ran a distance of 5 km in 30 minutes is 10000 meters(m) per hour(h).
<h3>What is the rate of speed?</h3>
The rate of speed is the rate at which the total distance is travelled in the time taken. Rate of speed can be given as,
Here, (d) is the distance travelled by the object and (t) is the time taken but the object to cover that distance.
Nancy ran a distance of 5 km in 30 minutes. There are 60 minutes in one hour. Thus, the time in hour for which Nancy ran is,
The meters in 5 kilometers is,
She ran 5000 kilometers in 0.5 hours. Thus, the speed of her is,
Thus, the speed of Nancy who ran a distance of 5 km in 30 minutes is 10000 meters(m) per hour(h).
