Final answer:

The correct calculation for the kinetic energy of an 88-kg scooter moving at 14 m/s, using the kinetic energy formula KE = ½mv², results in KE = 8624 J, which is closest to the provided option d: KE = 8600 J.

Step-by-step explanation:

To calculate the kinetic energy of an 88-kg scooter moving at 14 m/s, we use the kinetic energy formula:

KE = ½mv²

Where KE is kinetic energy, m is mass, and v is velocity. Plugging in the values:

KE = ½ × 88 kg × (14 m/s)²

KE = ½ × 88 kg × 196 m²/s²

KE = 44 kg × 196 m²/s²

KE = 8624 J

Since this value is not exactly matching any of the provided options but is closest to option d (8600 J), the correct answer is likely a result of a rounding difference in calculations. Therefore, the most accurate answer based on the given options is:

d. KE = 8600 J.
