    Answer:5.35N

    Explanation:

    Force is defined as the product of mass of an object and its acceleration.

    Acceleration is the change in velocity of an object with respect to time.

    Acceleration = velocity / time = 6.5/0.17 = 38.2m/s²

    since F = ma and mass is 140g

    140g to kg will be 140/1000 = 0.14kg

    F = 0.14 * 38.2

    F = 5.35N

    magnitude of the average force is 5.35N
