    the acceleration was negative the answer should be positive. Can someone else verify I'm on the right track or the answer is right?



    Thanks for the help Jim. After I looked it over again it seems to be right. I really appreciate it! :)
    Its not really being graded, just homework basically. This question was just reaaaallly bothering me because it seemed so simple, and I couldn't figure it out.

  3. ya i made sure it was in degree mode. After substituting everything in the equation i got 0squared = (4) squared + 2(9.87)(d) but Im' kind of stuck on that. (I know, my math is HORRIBLE) After trying to solve that I somehow ended up with 0squared=35.74(d) and thats where i got stuck, 0squared over 35.74 =d

    They dont need it.

    Use the equation vfinal^2 = vinitial^2+2*a*d

    Sum the forces Ffriction and Fgravity.

    Ffriction will be 20kg*.2*sin(20)*9.8m/s
    Fgravity will be 20kg*cos(20)*9.8m/s

    a will be negative if you make up hill positive so vinitial will be 4, vfinal will be 0, and a will be (Ffriction+fgravity)/20kg. Solve for d




    THANKS!!! B| OK so i got 5.978meters, is that totally fucked or is it just me?

  7. Ok anybody here who is good at physics i need some help. The problem is basically, a sled weighing 20kg is pushed with a velocity of 4m/s up a 20 degree incline with a 0.20 coefficient of friction. How far up the incline does the sled move? If anybody can help me solve this pleeeease do post.

    Well it looks like this could be a DZ.com match.

    Mellissa meet Mark. Mark meet Mellissa.

    A successful man is a man who can make more money than his wife can spend. A successful woman is a woman who can find such a man. Are you successful Mark? If so please PM Mellissa and keep DZ.com posted on the latest chapter of "As the prop turns".




    Wow. Im so confused. :D

  21. Ya im really into outdoor stuff so thats cool, I just hope there are some good lookin chicks up there, Ill be pissed if I move there for the next few years and its a total sausage fest.

  23. Calling all Vancouverites! Whats the nightlife like in vancouver? From what I hear its not a party city AT ALL compared to places like boston, philly, nyc, etc since there is only 1 or 2 universities. Ive been told after the sun sets the parties are almost non-existent. Thats the thing I love about places like Philly. You can walk through the streets around drexel/upenn etc at 1am and the streets are FILLED with people partying, literally every weekend. E-A-G-L-E-S chants going on left and right. Ahhh home.
