Question

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

Answer 1

Answer:

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
