Answer:

Step-by-step explanation:

The kinetic energy of a moving object is given by:

KE = (1/2)mv²

where KE is the kinetic energy, m is the mass of the object, and v is the velocity.

We can rearrange this equation to solve for the mass of the car:

m = 2KE / v²

Substituting the given values, we get:

m = 2(4.33 × 10^5 J) / (23 m/s)²

m = 2(4.33 × 10^5 J) / 529 m²/s²

m = 1.641 kg

Therefore, the mass of the car is approximately 1.641 kg.
