Question
A cyclist goes round the track of length 440m in 22s. Find the angle that the cyclist makes with the vertical.
Solution
Let r be the radius of track and v the speed of cyclist while circling the track.
Here,
Total length of track = 440m.
Therefore,
Time taken to complete the track is 22 s.
Therefore,
Now,
