Answer to Question #92560 in Mechanics | Relativity for Sridhar

Question

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

Answer 1

From the velocity diagram one can suggest that hypotenuse is the velocity of cyclist. See east and south direction are perpendicular to each other. Mean right triangle is well adopted.

Thus, the velocity of cyclist is

S²=V²+U²

S²=10²+10²

S=10√2 m/s

the cyclist is directed to the direction of north-east.
