Problem: A 1600-kg racing car with specially designed tires (u_sf = 1.2) is speeding down a track at 30.0m/s. Ahead, the track curves to the right, following a semicircle with a radius of 70.0m. Will the care be able to make it around the curve at this speed without skidding?
I need help for above problem and assume the curve is level, not banked.
