A straight river flows east at 10 mph. A motorboat heads from the south shore of the river at a heading of N30ºW toward the opposite shore at a speed of 20 mph and maintains that heading. Do the following: • Draw a diagram of the situation. Show your axes. • Express the velocity of the river as a vector in component form ai+bj. • Express the velocity of the motorboat relative to the water as a vector in component...

A ship (pt B) is trying to travel in a north-west direction (45
degrees from North). The water current (pt A) is flowing due east
with a velocity of 2 mph. The magnitude of the relative velocity of
the ship to the current is 5 mph. Express the direction of the
ship’s velocity vector relative to the water in unit vector
form.

Problem 3.41: Crossing the River, II. A river flows due south with a speed of 1.50m/s . A man steers a motorboat across the river; his velocity relative to the water is 4.40m/s . The river is 800m wide. Part A In which direction should the motorboat head in order to reach a point on the opposite bank directly east from the starting point? (The boat's speed relative to the water remains 4.40m/s .) Part B What is the velocity...
