Motion on Inclined Plain with Pulley

  1. Sep 21, 2008 #1
    1. The problem statement, all variables and given/known data
    Cart is on an inclined plain, attached to the cart is a weightless string going to a pulley attached to another mass. There is no friction.
    Cart Weight: 0.5Kg
    Mass Weight: 0.1Kg
    Plain Angle: 20 Degrees
    Diagram: See below

    Question: Determine Tension in string and acceleration.
    2. Relevant equations

    3. The attempt at a solution

    With the two equations I then made them both equal 5a and then used elimination, I got T=0.6582N and a=3.21m/s.
    I kinda doubt this is the right answer.

    Welcome to PF.

    I think you need to be consistent in how you assign signs between the two equations.

    The force on your weight should be more properly given by .1a = T - .98
