Question

A mass of 55 g hangs from a vertical spring how can you find the spring constant, is the answer a) 319n/m, b) 9.3n/m c) -0.00094 n/m d)320n/m

Answer 1

$mg=k\Delta x\to k=mg/\Delta x$

To determine the spring constant, we need to know its elongation.

Assume that $\Delta x=0.058\ (m)$ . So, we have

$k=mg/\Delta x=0.055\cdot9.8/0.058\approx9.3\ (N/m)$
