A case of fine glassware is loaded into a truck and sits on the floor. The truck drives along a street that follows along a circle that has a radius of 30.5 meters. The street is not banked. The coefficient of static friction between case of glass and the floor of the truck is 0.570. If the truck drives too fast, the case of glassware will slip and the glass will be damaged. How fast can the truck be moving without the box sliding?
