ok guys, I've worked it out ill post my solutions just incase anyone was interested or you have a similar question for part a It says its moving at constant velocity, therefore to overcome the 20N friction there must be a 20N force in the horizontal direction, therefore this allows us to...

so if the track exerts a force on a car in loop to loop, what exerts the force on the track?

look at it, as what's exerting the normal force on the person in the plane, which would be the chair.
