Ответ:

Коэффициент 1 пружины самый большой и равен 544 Н/м

Объяснение:

дельта l 1 = 1.1 см = 0,011м

l 2 = 1.5 см=0,015 м

l 3= 1.6 см = 0.016м

g = 10Н/кг

m =599г=0,599кг

k -?

Я так понимаю , раз пружина уже удлинилась и больше не удлиняется , то F тяж = F упр

F тяж=g • m= 10Н/кг•0,599кг= 5,99 Н

k = F упр : l

k1 = 5,99Н:0,011м=544 Н/м

k2 = 5,99Н : 0,015м =399 Н/м

k 3 = 5,99Н : 0.016м =374 Н/м

Получается первая пружина.
