Respuesta :

answer (c) 22000 J
1/2×2000kg×22ms
=22000 J

Answer:

Kinetic energy of the car is 484000 Joules.

Explanation:

It is given that,

Mass of the car, m = 2000 kg

Speed of the car, v = 22 m/s

We need to find the kinetic energy of the car. The formula of kinetic energy is given by :

[tex]E=\dfrac{1}{2}mv^2[/tex]

[tex]E=\dfrac{1}{2}\times 2000\times 22^2[/tex]

E = 484000 J

So, the kinetic energy of the car is 484000 Joules. Hence, this is the required solution.
