Question
when a weight of 100g is hung from the spring, its length is 9cm. when a weight of 150g is hung from it, its length is 11cm. what is the length of the spring when there is no weight hanging from it?
Answers
11 - L = (150/100)*(9-L)
11-L = 13.5 - 1.5L
0.5x = 2.5
L = 5 cm
11-L = 13.5 - 1.5L
0.5x = 2.5
L = 5 cm
