Distance covered by the train in 1 hour = 14km
Hence, to convert it into m/s we multiply 14 km/hr by 5/18.
we get distance traveled by the train i.e. length of the arc = 35/9 m/s = 700/3 m in 1 minute.
the radius of this segment = 700m.
Hence, using the formula ,
length of the arc = theta/360 x 2 x pi x radius
Solving this we get,
the angle traveled by the train as 19.1 degrees.
