The net force applied to a 2.0 kg steel ball causes ot to accelerate at 4.2 m/s/s. when the same force is applied to a 2.1 kg steel ball, what is the acceleration

4 m/s²

From the question, we are given;

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

Net force, F = 2.0 kg × 4.2 m/s²

                     = 8.4 N

Mass = 2.1 kg

Force = 8.4 N

But;

Force = mass × acceleration

Acceleration = Force ÷ Mass

                     = 8.4 N ÷ 2.1 kg

                    = 4 m/s²

Thus, the acceleration will be 4 m/s²
