Problem

A student plots kinetic energy on the

y

-axis against

v^{2}

on the

x

-axis for a moving body and obtains a straight line through the origin with a slope of

4\,\text{J\,s}^{2}\!\big/\!\text{m}^{2}

. What is the mass of the body? a)

4\,\text{kg}

2\,\text{kg}

8\,\text{kg}

6\,\text{kg}
