ok i have this problem
A train traveling at a constant speed rounds a curve of radius 375 m. A chandelier suspended from the ceiling swings out to an angle of 18.0° throughout the turn. What is the speed of the train?
so far i have 9.8sin(18)=(v^2)/375
v^2/R being force
and i got V=33.7 but it was wrong and just for kicks i switched from sin to cos and i still got the wrong answer I am not sure where I've gone wrong
thanks for your help,
johnny
