Chapter 3, Problem 36P
|| Crossing the river, I. A river flows due south with a speed of 2.0 m/s. A man steers a motorboat across the river; his velocity relative to the water is 4.2 m/s due east. The river is 800 m wide. (a) What is his velocity (magnitude and direction) relative to the earth? (b) How much time is required for the man to cross the river? (c) How far south of his starting point will he reach the opposite bank?

an airplane flies between two points on the ground that a re 500km apart. the destination is directly north of the origination. The plane flies with an air speed of 120 m/s. if a constant wind blows at 10.0 m/s. due west during the flight, what direction must the plane fly relative to the north to arrive at the destination.
An arrow is launched from ground level, with an initial speed of 27.2 m/s at an angle of 31.4° above the horizontal. Neglect air resistance, and take upward as the positive direction.
a) How much time is needed for the arrow to reach its maximum height, b) what is this maximum heightc) how long does it take to land on the ground againd) how far does it travel right before it lands.
|6) A river (R) flows due south with a speed of 2.20 m/s. A motor boat (B) steer across the rive. The velocity of the
