Question

A mass of 18.6 kg moving at 31.1 m/s has a kinetic energy of

Answer 1

Given data:

Mass;

`m=18.6\text{ kg}`

Velocity;

`v=31.1\text{ m/s}`

The kinetic energy is given as,

`K\mathrm{}E\mathrm{}=(1)/(2)mv^2`

Substituting all known values,

`\begin{gathered} K\mathrm{}E\mathrm{}=(1)/(2)*(18.6\text{ kg})*(31.1\text{ m/s})^2 \\ =8995.053\text{ J} \end{gathered}`

Therefore, the kinetic energy is 8995.053 J.
