Question

Two city buses are traveling at 24 miles per hour. The buses are the same model and year. One bus has 30 passengers. The other bus has 12 passengers. Which is the best prediction?(1 point)
Responses

The bus with 30 passengers will have less kinetic energy.
The bus with 30 passengers will have less kinetic energy.

The bus with 12 passengers will have less kinetic energy.
The bus with 12 passengers will have less kinetic energy.

The buses will have the same amount of kinetic energy.
The buses will have the same amount of kinetic energy.

The buses’ kinetic energies will depend on their routes.

Answer 1

The bus with 12 passengers will have less kinetic energy.

Reason: KE = 1/2 m v^2, and both buses have the same speed v. The bus with 12 passengers has less mass m, so its kinetic energy is smaller.
