Question

a car weighting 12kn has speed 20 ms-1 find it's kinetic energy​

Answer 1

Answer:

i think it is 2400J it may help you

Answer 2

$\color{red}\huge{\underline{\underline{GIVEN\dag}}}$

• $Mass(m)_{car}=12kg$
• $Velocity(v)_{car}=20ms{-1}$

$\color{red}\huge{\underline{\underline{SOLUTION\dag}}}$

We know that;

$\color{blue}\boxed{Kinetic\:Energy(KE)=\frac{1}{2}mv^{2}}$

$KE=\frac{1}{2}(12kg)(20m/s)^{2}$

$KE=6×400$

$\color{orange}\boxed{\therefore KE=2400Joules}$

HOPE THAT HELPS!!
