What is the kinetic energy of your car if it has a mass of 100kg and is driving

at a speed of 12m/s?

As we know,

`\boxed{ \boxed{kinetic \: \: energy = (1)/(2) mv {}^(2) }}`

where,

• m = mass = 100 kg

• v = velocity = 12 m/s

let's solve for kinetic energy of car :

• 
  `(1)/(2) * 100 * 12 * 12`

• 
  `100 * 12 * 6`

• 
  `7200 \: \: joules`
