1. F = k Δl Δl = F/k = 2 N / 100N/m = 0,02 m = 2 cm
2. F = k dl k = F / dl = 12 N / 0,06 m = 200 N/m
3. G = mg m = G/g = 200 N / 10 N/kg = 20 Kg
4. G medie = (G1 + G2 ) / 2 = m1g + m2g / 2 = g(m1+m2)/2
5. G = mg m = G / g = 60 N /10 N/kg = 6 kg
6. G = mg
G = 0,4 KN = 400 N m = 40 000 g = 40 kg g = G/m = 400 N / 40 kg = 10 N/kg
