    Explanation:

    a. Net force is mass times acceleration (Newton’s second law).

    ∑F = ma

    ∑F = (5.0 kg) (2.0 m/s²)

    ∑F = 10 N

    b. The net force is the sum of the individual forces.

    10 N = F − 5 N

    F = 15 N

    c. Friction force here is mgμ.

    mgμ = 5 N

    (5.0 kg) (10 m/s) μ = 5 N

    μ = 0.1
