The Attempt at a Solution
I've already technically completed question 4 part c, getting an answer of 8168 N downwards (which is what the answers say). However, this is implying that the net force, the gravitational force and the normal force are all acting in the same downward direction. This doesn't make sense to me because it doesn't include a force acting upon the car which is keeping it connected to the track. There has to be a force keeping the car in contact with the track, otherwise it would just fall off. Is there an extra force which would be acting in this situation which has been exempted from the question to prevent the question form becoming too complicated? An explanation for this would be much appreciated.
Thank you all for you time.
