Concept explainers
The reading of the scale at its peak.
Answer to Problem 88GP
Solution: 44,200 N
Explanation of Solution
Given:
The compression of the spring
Weight is
Height,
Formula Used:
The potential energy of the spring,
Our potential energy
The final compression
Calculations:
The spring constant is:
Therefore, the spring potential energy is:
When you jump on the scale, the potential energy it creates is:
Therefore, the total energy is:
If the new compression of the spring is
Therefore, the final reading of the scale will be
Conclusion:
The scale will read approximately 44,200 N.
