WHat isn’t required to accelerate a 180,000. kg train engine at a rate of 2.0 m/s
To accelerate a 180,000 kg train engine at a rate of 2.0 m/s², the following are not required:
1. The color of the train engine: The color has no effect on its acceleration.
2. The number of wheels on the train engine: The number of wheels does not influence its acceleration; rather, factors like the friction between the wheels and the track are important.
3. The destination of the train: The acceleration does not depend on the destination; it is determined by the applied force.
4. The time it takes to reach the desired acceleration: The time is not necessary to determine the requirements for acceleration but is dependent on the force applied and the resulting acceleration.
5. The number of passengers on the train: The number of passengers does not directly affect the acceleration; it might indirectly impact the required force needed due to the weight of the passengers.
The factors that are necessary for calculating the required force to accelerate the train are:
1. Mass of the train engine: The mass of the object being accelerated is essential in determining the force required.
2. Desired acceleration: The rate of acceleration determines the force needed.
3. Frictional forces: The friction between the train engine's wheels and the track impacts the force required to overcome it.
4. Resistive forces: Air resistance and other resistive forces also affect the force required.
5. Net force: The net force acting on the train engine needs to be larger than the sum of all opposing forces for it to accelerate at the desired rate.
