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 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. The buses’ kinetic energies will depend on their routes. The bus with 30 passengers will have less kinetic energy.
The buses will have the same amount of kinetic energy.
The bus with 30 passengers will have less kinetic energy.
To determine which bus will have less kinetic energy, we need to understand the formula for kinetic energy and how it is related to the mass and velocity of an object. The formula for kinetic energy is:
Kinetic Energy (KE) = 0.5 * mass * velocity^2
In this case, we are given that both buses are traveling at the same velocity of 24 miles per hour. Therefore, the only factor that will affect their kinetic energies is their masses.
The bus with 30 passengers will have a greater mass compared to the bus with 12 passengers since mass is directly proportional to the number of passengers. As a result, the bus with 30 passengers will have more kinetic energy based on the formula.
Therefore, the best prediction is: "The bus with 30 passengers will have more kinetic energy."
