    4 m/s²

    Explanation:

    From the question, we are given;

    Mass of the ball is 2.0 kg Acceleration of the ball is 4.2 m/s²

    With the above information, we can calculate the force applied to the ball.

    From the second newton's law of motion, F = ma Therefore;

    Net force, F = 2.0 kg * 4.2 m/s²

    = 8.4 N

    We are required to determine the acceleration when the same force is applied to a steel ball with a mass of 2.1 kg.

    Mass = 2.1 kg

    Force = 8.4 N

    But;

    Force = mass * acceleration

    Rearranging the formula;

    Acceleration = Force : Mass

    = 8.4 N : 2.1 kg

    = 4 m/s²

    Thus, the acceleration will be 4 m/s²
