Answer:
4 m/s²
Step-by-step 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
Acceleration = Force ÷ Mass
= 8.4 N ÷ 2.1 kg
= 4 m/s²
Thus, the acceleration will be 4 m/s²
