Physic question - Vector addition
I need help with the vector addition, I tried many times but always got the wrong answer, Thank you in advance.
The problem as follow:
Select an answer for each... below.
For an observer on shore, the speed of the boat for F is... for D
Time to row across for C is... for J
Time to row across for K is... for B
The distance traveled in crossing for J is... for B
Time to row across for J is... for B
And the blank should be filled in with equal to, larger than, or less than.
The follow link is a similar picture except in my pic, the A is river velocity, and following from the top to the bottom is J, C, D, F, H, K, B.
