answer A,B,C and D
A canoe goes direatly across a river at \( 4.5 \mathrm{~m} / \mathrm{s} \). The water flows \( 9+2.5 \mathrm{~m} / \mathrm{s} \) and is \( 698 \mathrm{~m} \) across. a What is the resultant verocity of the boat (magnitude and direction) b How lang does it take the canve to cross the river C How far downstream is the canoe's landing point? D. How long would it take the cance to cross the river if there were no current?
Expert Answer
a. Let directly across the river be the positive y direction and along the current be the positive x direction The resultant velocity of the boat is v
