A 1,859-kilogram roller coaster car is approaching a valley. At its bottom, the valley can be described by a circle with radius 7 m.
Find the speed required at point A, such that the normal force acting on the car in point B is 219% more than the weight.
Below answer with the required speed at point A with units of m/s.
Make sure to practise how to explain your work and also how to evaluate your result. Draw proper diagrams.
