A railway train is travelling on a circular curve of 1500 metres radius at the rate of 66km/hr. Through what angle has it turned in 10 seconds?

Explanation

Radius of circular curve, `R=1500 m`


Speed of trains, `S=(66 km) / (hr)`


Converting speed of train into `{m} / {sec}`


Speed of train `=66 times frac{5}{18}=frac{110}{3} {m}/ {s}`


Time travelled, `t=10 sec`


Distance converted, `d=s times t`



`=frac{110}{3} times 10=frac{1100}{3} m`
