- Hi I've been trying this question but keep getting the wrong answer any help would be appreciated
- Relevant Equations
- F=ma
Thanks for that mate just redid it and got the right answer will definitely be more thorough with my calculations next time!Lnewqban said:I can see two errors:
* Revise your math regarding resultant net force.
* Incorrect equation for calculating distance.
Please, see:

When a train is traveling up a hill, gravity is working against it, causing it to slow down. This means that the train's deceleration will be greater compared to when it is traveling on a flat surface.
The main factors that affect train deceleration when traveling up a hill are the grade of the hill, the weight of the train, and the friction between the train's wheels and the tracks.
Train deceleration when traveling up a hill can be calculated using the formula: a = g(sinθ - μcosθ), where a is the deceleration, g is the acceleration due to gravity, θ is the grade of the hill, and μ is the coefficient of friction between the train's wheels and the tracks.
The higher the speed of the train, the greater the deceleration will be when traveling up a hill. This is because the train will have more momentum and will need to overcome a greater force of gravity to slow down.
Yes, train deceleration can be controlled by the train's braking system. The train operator can adjust the amount of braking force applied to slow down the train, depending on the grade of the hill and the speed of the train.
