In the figure, there is a schematic representation of the route followed by a roller coaster. The vehicle with mass m starts to descend with velocity v after climbing a hill of height h. The tool then travels through the vertical circle of radius R, p the horizontal curve of radius, and finally crosses the hills of radius r. Assuming that there is friction between the vehicle and the surface only in the horizontal curve a)What is the reaction force acting on the vehicle at the top of the vertical circle? b)What is the reaction force acting on the vehicle at the lower point of the vertical circle? c)If the friction coefficient is c, what is the maximum speed that the vehicle can pass through the curve. (m= 140kg V=2 m/s h=110m R=20 m p=13m c=0.6)
