    Answer: Mass of the first ball is 5kg; Mass of second ball is 3.75kg

    Explanation:

    Given that:

    Force of first ball = 15 N

    Acceleration of first ball = 3 m/s2

    Mass of first ball M1 = ?

    Force of second ball = 15N (same force)

    Acceleration of second ball = 4 m/s2

    Mass of first ball M2 = ?

    A) Since force is a product of mass of a substance by the acceleration by which it moves: Force = Mass x acceleration

    For first ball, Force = M1 x A

    15 N = M1 x 3 m/s2

    M1 = 15N/3 m/s2

    M1 = 5 kg

    B) For second ball, Force = M2 x A

    15 N = M2 x 4 m/s2

    M2 = 15N/4m/s2

    M2 = 3.75kg

    Thus, the mass of the first ball is 5kg while the second ball is 3.75kg
