When does a cyclist appear to be stationary with respect to another moving cyclist ?

Wht does Pole Star appear to be stationary in the sky ?

Wind is blowing from south at 10 m/s but to a cyclist it appears to be blowing from the east at 10 m/s. The cyclist has a velocity

Raindrops are falling vertically with a velocity 10 m//s . To a cyclist moving on a straight road the rain drops appear to be coming with a velocity of 20m//s . The velocity of cyclist is :-

A train moving at 15 m/sec takes 20 seconds to pass a cyclist moving in the same direction as that of the train. How much time will be train need to pass the cyclist, if the cyclist moves in a direction opposite to that of the train and if the speed of the cyclist is 5m/sec and the length of the cycle is 1 m? 9. 95 s e c b. 10 s e c c. 10. 05 s e c d. 12 s e c

A 10-km long straight road connects two towns A and B , Two cyclists dimultaneously start one from town A and the other from town B .On reaching the opposite town, a cyclists simmediaeately retrns to his starting town wheras the other cyclist takes some rest and then returns to his starting town. Both of them can ride at speed 20 km h^(-1) in absence of wind but during their whole journey uniform wind from town A and B increase the speed of it decreases the speed of the cyclist going against the wind Both the cyclisrs meet twice, first at 2 km and then 6 km away from one of the tomns. If which town and for what perild does a cyclist rest ?

A person standing on one side of a road blows a whistle which has a frequency of 600 Hz . A cyclist passes at 16 kilometre per hour. What does the frequency of the whistle appear to be to the cyclist before and after passing ? (Velocity of sound in air = 350 ms^(-1) )

Why does a cyclist bend inwards while riding along a curved road?
