A bike of 600 kg mass has a kinetic energy of 84 kJ. Find its speed (in m/s).

Kinetic energy is the energy that a body possesses as a result of its motion.

$K=\frac{1}{2}m{v}^2$

Here, $m=$ the mass of the body and $v$ = velocity of the body

Given that:

$\mathrm{Mass}\left(m\right)=600\mathrm{kg}$

Kinetic Energy$$\begin{gathered} \left(\mathrm{KE}\right)=84k \\ =84\times {10}^3 \end{gathered}$$.

Use the provided kinetic energy formula:

$84\times {10}^3=\frac{1}{2}\times 600\times v^2$

$v^2=\frac{84\times {10}^3}{300}=280$

$v=16.73$

Speed of the bike$=16.73 m/s$
