Kinetic energy is given by the formula, $\mathrm { E } _ { \mathrm { k } } = \frac { 1 } { 2 } \mathrm { mv } \mathrm { v } ^ { 2 }$ joules, where $\mathrm { m }$ is the mass in kilograms and $v$ is the velocity in metres per second. Ev aluate the velocity when $\mathrm { E } _ { \mathrm { k } } = 576 \times 10 ^ { - 3 } \mathrm {~J}$ and the
mass is $5 \mathrm {~kg}$ .
