Document Summary

Phys 101: physics for the life sciences lecture 7: kinematics iv. It is crossing a river at a speed of 10 km/h relative to the water. The water has a uniform speed of 5 km/h due east as measured by somebody on the shore. Determine the velocity of the boat relative to the same observer on the shore. = velocity of the river = 5 km/h. V br= velocity of the boat relative to the water = 10 km/h. = 11. 2 km/h @ 63. 4 n of e. A boat whose speed in still water us 1. 70 m/s must cross a river of width 260 m. the boat wants to arrive at a position on the opposite shore 110 m upstream from where it started. In order to do this the sailor must head the point at a 45 upstream angle.

A boat crossing a wide river moves with a speed of 13.0 km/h relative to the water. The water in the river has a steady speed of 6.00 km/h due north relative to the earth.
a) If the boat heads due west, determine the speed of the boat relative to an observer standing on the shore.

b) What is the angle made between the velocity of the boat relative to the observer and the west direction.

The velocity of a Boat A straight river flows east at a speed of 10 mi/h. A boater starts at the south shore of the river and heads in a direction 60° from the shore (see the figure). The motorboat has a speed of 20 mi/h relative to the water. 
(a) Express the velocity of the river as a vector in component form.
(b) Express the velocity of the motorboat relative to the water as a vector in component form.
(c) Find the true velocity of the motorboat.
(d) Find the true speed and direction of the motorboat. 

A boat crossing a river moves with a speed of 3 m/s relative to the water.
The water in the river has a uniform speed of 4 m/s due east relative to the Earth. The river is 120 m wide. If the boat heads due north (a) how long does the crossing take? (b) Calculate the magnitude and direction of the velocity of the boat with respect to the Earth.
