a river flows due east at 15 ms a boat crosses the river from from the south shore to the north

a. The velocity of the boat as viewed by an observer on shore is the vector sum of the velocity

Question

A river flows due east at 1.5 m/s. A boat crosses the river from the south shore to the north shore by maintaining a constant velocity of 10.0 m/s due north relative to the water. a. What is the velocity of the boat as viewed by an observer on shore? b. If the river is 325 m wide, how far downstream is the boat when it reaches the north shore? The pilot of an aircraft wishes to fly due west in a 50.0 km/hr wind blowing toward the south. The speed of the aircraft in the absence of the wind is 205 km/hr. a. In what direction should the aircraft head? b. What should its speed relative to the ground be? A hunter wishes to cross a river that is 1.5 km wide and that flows with a speed of 5.0 km/hr. The hunter uses a small powerboat that moves at a maximum speed of 12 km/hr with respect to the water. What is the minimum time necessary for crossing?
