As we know,

[tex]\boxed{ \boxed{kinetic \: \: energy = \frac{1}{2} mv {}^{2} }}[/tex]

where,

  • m = mass = 100 kg

  • v = velocity = 12 m/s

let's solve for kinetic energy of car :

  • [tex] \dfrac{1}{2} \times 100 \times 12 \times 12[/tex]

  • [tex]100 \times 12 \times 6[/tex]

  • [tex]7200 \: \: joules[/tex]
