Question

a train is moving on a circular curve of radius 1500 metre at the rate of 66 kilometre per hour through what angle has it turned in 10 second​

Answer 1

Answer:

a circle with radius r = 1500 m

a train is moving on a circular curve at rate of 66km per hour

therefore speed = 66 km per hr = 66*1000 / 3600

=18.33 m per sec

1 sec the distance covered= 18.33 m

10 sec................................= 18.333*10= 183.33m

now as we know theta (i.e angle) = arc/ radius

= 183.33 / 1500 =0.122 radians is the required angle covered
