two city buses are traveling at 24 mph the buses are the same model and year one bus has 30 passengers. the other bus has twelve which is the best prediction
the buses kinetic energies will depend on their routes
the buses will have the same amount of kinetic energy
the bus with 30 passengers will have less kinetic energy
the bus with 12 passengers will have less kinetic energy
Well, considering that both buses are traveling at the same speed, the one with 30 passengers will have more kinetic energy. You see, with all those extra people bouncing around in the bus, it's like having a party on wheels! So, yeah, the bus with 30 passengers will definitely have more kinetic energy and maybe a bit more fun too. Who doesn't love a party bus, right?
To determine the best prediction regarding the kinetic energies of the buses, we need to understand the factors that affect kinetic energy. Kinetic energy (KE) is directly proportional to the mass and the square of the velocity of an object.
In this scenario, the buses are the same model and year, so their masses are likely to be similar. Therefore, we can assume that the mass of the two buses is roughly equal.
On the other hand, the velocity is given as 24 mph for both buses. Since the velocities are the same, the only remaining factor that could affect the kinetic energy is the number of passengers.
More passengers mean more mass, which results in more kinetic energy. So, based on this understanding, we can make the following predictions:
1. The buses' kinetic energies will depend on their routes: This statement does not provide any specific information to make a prediction about the relative kinetic energies of the buses.
2. The buses will have the same amount of kinetic energy: This prediction is incorrect because the number of passengers can affect the kinetic energy, and the buses have different passenger counts.
3. The bus with 30 passengers will have less kinetic energy: This prediction is incorrect because more passengers mean more mass, leading to more kinetic energy.
4. The bus with 12 passengers will have less kinetic energy: This prediction is the best choice because fewer passengers mean less mass, resulting in less kinetic energy.
Therefore, the best prediction is that the bus with 12 passengers will have less kinetic energy compared to the bus with 30 passengers.
