A 1kg ball rolls along a circular track that is banked at 20 degrees. The normal force on the ball is 10.43N, tilted inward. The radius of the track is 10m. a. What is the net force on the ball (include direction)? b. How fast is the ball going for it to complete the turn? possible equations= radial acceleration=v^2/r, total radial force mv^2/r, and as for where i am, i don't really know where to start! to find the net force, i know i start with the 10.43N acting on it. I don't know if the 20 degrees comes into play at all or not. any help is greatly appreciated!
