(a) When a cyclist travels along a straight road from North to South at a constant speed of 6.5 m s, the wind appears to come from a direction West 45 South. 2. When he returns along the same road at the same constant speed, the wind appears to come from a direction East 45 South. Find, the magnitude and direction of the velocity of the wind. A ship B is steaming on a straight course South-East at a uniform speed of 15 km/h. Another ship A, is a distance 10 km due North of B, and steams at a speed of 12 km/h. (b) Find, the course that A must steer to get as close to B as possible, and their minimum distance apart.
