5.102You are riding in a school bus. As the bus rounds a flat curve at constant speed, a lunch box with mass 0.500 kg, sus- pended from the ceiling of the bus by a string 1.80 m long, is found to hang at rest relative to the bus when the string makes an angle of 30.0° with the vertical. In this position the lunch box is 50.0 m from the curve's center of curvature. What is the speed v of the bus?
