Question

What is the kinetic energy of a car with a mass of 1,6000 kg moving at 20 m/s

Answer 1

3.2 MJ or 3200KJ or 3200000J

Step-by-step explanation:

To calculate the Kinetic energy, we use the following formula:

`\alpha ke \: = (1)/(2) m {v}^(2)`

Where, ∆KE = change in kinetic energy

m = mass

v = velocity

From our question, we have

m = 16000 kg

v = 20 m/s

Substitute the values into the equation gives,

`ke \: = \: (1)/(2) \: * \: 16000 \: * \: {20}^(2) \\ = 3200000 \: joules`

Therefore, the Kinetic energy of the car

∆KE = 3200000 J = 3200 KJ = 3.2 MJ

And we have the solution to our problem.
