A boat launches from one shore of a river heading upstream at an angle of 60o to the shore. The boat's speed, relative to the water, is 9 mph and the current of the river flows against the course of the boat in such a way that the boat ends up traveling directly across the river (L to the shore). How fast must the current of the river be flowing if...

П. On a river bank, Point B is 6.0 km downstream from Point A. Two friends must make the round trip from Point A to Point B and then return to Point A. One rows a boat at a constant speed of 8.00 km/h relative to the water, the other walks on the shore at a constant speed of 3.50 km/h. The velocity of the...

3.) Vectors are useful in physics and engineering. Force is one example of a vector quantity. Definition. If several forces are acting on an object, the resultant (net) force experienced by the object is the vector sum of these force. Below is information about two forces acting on an airplane. Force 1: Suppose that the wind is blowing 45 degrees Northwest at a speed of...

1. A 0.25 km wide river has a uniform flow speed of 4.2 m/s toward the east. It takes 23 s for a boat departing from the south bank to travel straight across the river to a position directly north of its departure. a) In what direction must the boat be pointed so as to accomplish this? Express your final answer relative to the North direction. (Hint: Start by drawing a right triangle representing the vector addition)...

A river flows due south with a speed of 4.5 m/s. A man steers a motorboat across the river. His motor can push the boat through water at a speed of 7 m/s. Starting on the western shore, he points the nose of his boat due east. The river is 500 m wide. What is his speed relative to the ground? 8. b. 3.95 m/s d....
