    Hey guys I have this question I am attaching.

    The acceleration of a car/cart down a slope?

    What do you get? No need to show workings, just want to see if other people get the same answer as me, since I made the question up.

    Whats the popular opinion. ?

    Are the forces Wii and the perpendicular W caused by the weight of the car (ie are they the components of weight?) Or are they separate

    The car has a weight W in Newton given by it's mass, so hypotenuse newton value of that triangle (W) would be the weight of the car in free fall.

    So that's just gsin40 - 1

    Answer should be in meters per second^2

    m/s^2

    To avoid confusion here, the WII force is the same force, I have just labeled twice (it on the slope and the triangle in the vector diagram). There is not 2 different WII's

    The Forces are named in the car picture cartoon picture
    There is only these forces to worry about.

    W_I_
    WII
    W
