Document Summary

28 september 2010: relative motion (15 points). A 200-m-wide river has a uniform flow speed of 1. 1 m/s through a jungle and toward the east. An explorer wishes to leave a small clearing on the south bank and cross the river in a powerboat that moves at a constant speed of 4. 0 m/s with respect to the water. During volcanic eruptions, chucks of solid rock can be blasted out of the volcano; these projectiles are called volcanic bombs. The figure shows a cross section of mt. Ignore, for the moment, the effects of air on the bomb"s travel. (b) what would be the time of flight: newton"s laws (20 points). Determine a formula for the magnitude of the force exerted on the large block ( ) in the figure so that the mass does not move relative to. Assume does not make contact with : friction (25 points).

A 480-m-wide river has a uniform flow speed of 1.3 m/s through a jungle and toward the east. An explorer wishes to leave a small clearing on the south bank and cross the river in a powerboat that moves at a constant speed of 4.1 m/s with respect to the water. There is a clearing on the north bank 65 m upstream from a point directly opposite the clearing on the south bank. (a) At what angle, measured relative to the direction of flow of the river, must the boat be pointed in order to travel in a straight line and land in the clearing on the north bank? (b) How long will the boat take to cross the river and land in the clearing?

A 200 m wide river has a uniform flow speed of 1.1 m/s through a jungle and toward the east. An explorer wishes to leave a small clearing on the south bank across the river in a powerboat that moves at a constant speed of 4.0 m/s with respect to the water. There is a clearing on the north bank 82 m upstream from a point directly opposite the clearing on the south bank. (A) In what direction must the boat be pointing in order to ravel in a straight line and land in the clearing on the north bank? (B) How long will the boat take to cross the river and land in the clearing?
