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.
