9 Una tavola di legno, lunga 2,00 m e di massa trascurabile,
è fissata a un estremo, attorno al quale è libera di ruotare.
All'altra estremità è agganciata a una grossa molla che ha
costante elastica pari a 2000 N/m.
La tavola si dispone orizzontalmente quando una persona
si trova a 0,50 m dalla molla. Supponendo che quest'ulti-
ma si sia allungata di 24 cm, trova la massa della persona.
