A train traveling at a constant speed rounds a curve of radius 200 m. A chandelier suspended from the ceiling swings out to an angle of 17.0° throughout the turn. What is the speed of the train?
Again, use your formulas. Simple plug-n-chug with radial/angular force.
A subway train is traveling at 80km/h when it approaches a slower train 49m ahead traveling in the same direction at 24km/h
