10. A train traveling at a constant speed rounds a curve of radius 250. m. The curve starts with the train heading north and ends with the train heading west. A chandelier suspended from the ceiling swings out to an angle of 21.0 throughout the turn. a) What is the train's speed? (100 km/h). b) What is the train's acceleration at the very beginning of the turn, in all its vector glory? (4 m/s2 [W]) c) What is the magnitude of the effective gravity aboard the train? (10 N/kg) d) What is the tension in the wire supporting the 45.0 kg chandelier? (500 N) 10. A train traveling at a constant speed rounds a curve of radius 250. m.
