Question 44239
The distance D that a spring is stretched by a hanging object varies directly as the weight W of the object.
{{{D/W = D/W}}}
If a 26-kg object stretches a spring 28cm, find the distance the spring is stretched when the weight is 21kg?
{{{D/W = D/W}}}
{{{28/26 = D/21}}}
{{{588/26 = D}}} about 22.6cm
