Dobry den,
vedel by mi niekto pomoct s tymto prikladom?
Pružina má tuhosť 150 N/cm. Aká je hmotnosť zaveseného telesa, ak amplitúda pri kmitavom pohybe je xm = 25 cm a rýchlosť pri prechode rovnovážnou polohou je v1 = 12 m/s?
Skusam ho vypocitat roznymi sposobmi, ale neviem sa dopracovat k vzorcu, kde by som mal len jednu neznamu a vedel vypocitat hmotnost /m/.
Takisto neviem ako a kde presne dosadit xm.
Dakujem
