Homework Statement
car is on a banked curve of angle 18o, radius 70m. Mass of car = 1020kg and weight is taken as 1.0x10^4 N. Find the resultant force and the normal force N when the car is at the design speed.
Homework Equations
force diagram equations
The Attempt at a Solution
I calculated Normal force to be 10514.6N
I calculated the resultant force to be the component of the normal force towards the centre of the banked curve, and got 3249.2N
I think design speed just means max speed the car can safely travel around the curve at, I calculated this to be approx. 14.9 m/s but i could be quite wrong.
Are there things I'm forgetting to consider? is this exactly what the question asks for?
