Hooke's Law. The distance d when a spring is stretched by a hanging object varies directly as the weight w of the object. If the distance is 23 cm when the weight is 3 kg, what is the distance when the weight is 5 kg? I need the answer badly and I do not understand how to do the problem.
ok quic anser is 25
that answer is incorrect
Thats not correct either
3 kg stretches the spring by 23 cm so, each kg stretches it by 23/3 cm
so, 5 kg will stretch it 5 times that much 5 * 23/3 = 38.33
naw the correct answer was 115/3
