Question

a train is moving on a circular curve of radius 1500 m at the rate of 66 km\ h . through what angle has it turned in 10 second.​

Answer 1

Answer:

r = 1500 m

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

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

=18.33 m per sec

1 sec the distance covered= 18.33 m

10 sec. the distance covered = 18.333 × 10 = 183.33m

theta (i.e angle) = arc/ radius

=183.33 / 1500

=0.122 radians

this is your answer..

thanks..
