You'd need to break your theoretical initial velocity and angle of projection down into the initial X and Y components.
(R being initial velocity magnitude, O being initial angle)
Vox R x cosO
Voy R x sinO
Then, you'll also have to break down your equations for motion into X and Y...
Alright, so now on to the net x-forces:
(W being weight, T being tension)
-W + T = ma
-85N + T = 85/9.8 x -27.9
then T = -156.99
... However, I didn't think tension could be negative, and 156N is the wrong answer.
Is W is the same direction of T then?
Hrm. It might have helped that I didn't picture the fish and line similar to the classic elevator problem... (I don't fish.)
Acceleration, going back to vectors and 1-D motion, comes to -27.9 m/s^2; if I did things right. Does that seem too fast?
v(t) = Vo + at
0= 2.5 + at
t = -2.5/a...
Alright, this one seems too easy to be hard! But, I've spent a lot of time on it and I'm stuck, sad to say. Maybe someone can help please??
What min strength is needed for a line that is to stop a fish of 85N in 0.112m if the fish is initially drifting at 2.5 m/s? (Assume constant...
[FONT=Century Gothic]Woo. Nevermind the rest of this message. I figured it out =))))
Hello all :)
Am having brain fart, I need help (obiviously) from the experts! All the tutorials and examples about the classic boat crossing a river aren't helping me with this problem.
