The kinetic energy of the car is [tex]2.0\cdot 10^5 J[/tex]
Step-by-step explanation:
The kinetic energy of an object is the energy possessed by an object due to its motion. Mathematically, it is given by:
[tex]E_k = \frac{1}{2}mv^2[/tex]
where
m is the mass of the object
v is its speed
For the car in this problem, we have:
m = 1000 kg is the mass of the car
v = 20 m/s is its speed
Substituting into the equation, we find its kinetic energy:
[tex]E_k = \frac{1}{2}mv^2 = \frac{1}{2}(1000)(20)^2=2.0\cdot 10^5 J[/tex]
