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

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
