116.A launch flies between two points A and B on the opposite banks of a river always following the line AB. The distance S between points A and B is 1200m. The velocity of the river current v=1.9m/s is constant over the entire width of the river. The line AB makes an angle a=60 degree with the direction of current. With what velocity u and at what angle B to the line AB should the launch move to cover distance AB and back in time t=3min should |
