    8 Dogs pull a sled with Mass 200Kg. Friction is 0.1 and acceleration is 1.5 m/s2. Assume equal force for each Dog. What is the Force for each Dog?

    F = ma

    let P = pulling force ( + x-axis)
    and Fr = friction force (- x-axis)

    P - Fr = ma
    P - 0.1 = 200 * 1.5
    P = 300 - 0.1 = 299.9 N

    P is the force of pulling of the 8 dogs, for each dog its P/8 Newton.
