Unit 3: Motion in Two Dimensions
Problem Set B
(Referring to the previous problem.) If the river is 239 m wide and the boat heads directly across it, then how much time (in seconds) does it take the boat to reach the opposite shore?
A discussion of the principlesof relative motion and of the basic strategy for solving such problems is provided on the Set B Overview Page.
Detailed information about and discussion of the strategies for solving riverboat problems and other relative velocity problems is provided online at The Physics Classroom.
