Pertanyaan
Example A 3.2-kg block is hanging stationary from the end of a vertical spring that is attached to the ceiling.The elastic potential energy of this springblock system is 1.8 J. What is the elastic potential energy of the system when the 3.2-kg block is replaced by a 5 .0-kg block?
Solusi
Jawaban
**Energi potensial pegas ketika blok digantikan dengan massa 5.0 kg adalah sekitar **25.7 J**.
Penjelasan
**Energi potensial pegas (EPE) dalam sistem pegas-blok diberikan oleh rumus:
