Given:
The combined mass is
[tex]m=550.0\text{ kg}[/tex]The speed is
[tex]v=15.98\text{ m/s}[/tex]Required: find the kinetic energy.
Explanation:
To find the kinetic energy we will use the formula that is given as
[tex]K.E=\frac{1}{2}mv^2[/tex]Here,
[tex]m[/tex]is the mass and
[tex]v[/tex]is the speed.
Plugging all the values in the above relation, we get
[tex]\begin{gathered} K.E=\frac{1}{2}mv^2 \\ K.E=\frac{1}{2}\times550.0\text{ kg}\times(15.98\text{ m/s})^2 \\ K.E=0.5\times550.0\text{ kg}\times255.36\text{ }(\text{m/s}^)^2 \\ K.E=70224.11\text{ J} \end{gathered}[/tex]Thus, the kinetic energy is 70224.11 J.
