Little Nellie Newtons Force Problems

  1. Oct 23, 2008 #1
    Hi,
    I have to do the Nellie Newton Problems on this Page here:
    Link!

    We just started with Forces and I tried to solve the problems but I´m not completely sure if my answers are correct. If there are mistakes it would be nice if you could tell me why and what I did wrong.

    Here are my answers:

    1. 300N
    2. 300N each
    3. 150N each
    4. 100N each
    5. 150N
    6. 100N


    Thank you,
    jawo3

    Looks like you did very well....until you got to the last one. What's your reasoning behind your answer to #6?

    I agree with all except #6/F.

    Perhaps if you explain your reasoning for that last one, I could give a hint that would help you out.

    edit: PhanthomJay beat me to it.

    Does 75N sound better?

    If it's correct, I think I know what I did wrong. If I'm right I just have to devide the force twice by two instead of deviding it by three.

    Otherwise please explain me how I can solve these kind of problems because our teacher did not.

    Nope, not 75N.

    Try drawing a diagram showing the forces acting on Nellie.
