A 103.8kg wood block is resting on a wooden floor. You can push a maximum of 1061.5 N on the block without moving it. If you continue to exert this push force once the block starts to move, find the magnitude of its acceleration (in m/s2) ? (Coefficent of Kinetic friction between wood blocks is 0.3)

    7.286 m/s²

    Explanation:

    Let's say P is the applied force and F is the force of friction. Remember that friction is the product of normal force and the coefficient of friction (F = Nμ).

    Apply Newton's second law in the y direction:

    ∑F = ma

    N - mg = 0

    N = mg

    Apply Newton's second law in the x direction:

    ∑F = ma

    P - F = ma

    P - Nμ = ma

    Substitute and solve for a:

    P - mgμ = ma

    a = (P - mgμ) / m

    Given P = 1061.5 N, m = 103.8 kg, g = 9.8 m/s², and μ = 0.3:

    a = (1061.5 - 103.8*9.8*0.3) / 103.8

    a = 7.286 m/s²
