Answer:

The answer to your question is the letter C. 1,200,000 J

Explanation:

Data

mass = 2300 kg

speed = 32 m/s

Kinetic energy = ?

Kinetic energy is the energy that an object possesses due to its motion.

Formula

    Ke = 1/2 mv²

Substitution

    Ke = 1/2 (2300)(32)²

Simplification

    Ke = 1/2 (2300)(1024)

Result

    Ke = 1177600 J ≈ 1, 200, 000 J
