The kinetic energy of the car is [tex]4.5\cdot 10^5 J[/tex]
Explanation:
The kinetic energy of an object is the energy possessed by the object due its motion. 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 its mass
v = 30 m/s is its speed
Substituting into the equation, we find the kinetic energy of the car:
[tex]E_k = \frac{1}{2}(1000)(30)^2=4.5\cdot 10^5 J[/tex]
