Problem

A student records the periods of oscillation for different masses attached to the same horizontal spring. Mass (kg):

0.10\quad 0.20\quad 0.30\quad 0.40

Measured period (s):

0.63\quad 0.89\quad 1.09\quad 1.26

Using these data, what is the best estimate for the spring constant? (a)

6.3\,\text{N}\!\cdot\!\text{m}^{-1}

(b)

3.2\,\text{N}\!\cdot\!\text{m}^{-1}

(c)

1.0\times10^{1}\,\text{N}\!\cdot\!\text{m}^{-1}

(d)

2.0\times10^{1}\,\text{N}\!\cdot\!\text{m}^{-1}
