Hi, I was trying to solve the following problem which was assigned to me in my Kinematics course.
I found this solution for it. I understand the concept of relative velocity of the boat to the flowing river but what I really cannot understand is the trig part, of Vb/r :
Vb/r = 5cos(theta)i - 5sin(theta)j
Where did the cos(theta) and sin (theta) come from? I understand that this is represented in vectorial form, but I cannot visualize the direction of this velocity. Probably a graphical solution would solve my problem.
Thanks in advance
