Unformatted text preview: ma n Write out equations of motion. Since the Fy’s will just have one unknown, let’s do that one first. Now sum forces in the normal direction When is velocity a min? Car won’t slide if just sitting there. How about for max velocity? IC4.2 – Race Car on a Banked Turn Draw the FBD and MAD Solution: Problem Type: Find : Given: μ= 0.90,ρ = 1200 ft v when friction force = 0, Min and Max Speeds Particle Kinetics ( F =m a ) Sketch: FBD MAD...
