Given:
- Mass of each ball = 2 kg
- Velocity of the balls = 10 m/s
- Spring constant = 4 N/m

Acceleration produced in each ball:

To find the acceleration produced in each ball, we can use the equation of motion:

Force = mass × acceleration

The force acting on each ball is provided by the compressed spring. According to Hooke's Law, the force exerted by a spring is directly proportional to its displacement from the equilibrium position. The equation for the force exerted by a spring is given by:

Force = spring constant × displacement

Hence, the force exerted by the spring on each ball can be calculated as:

Force = 4 N/m × displacement

Since the balls are initially at rest, the displacement of the spring is equal to the initial compression of the spring. Let's assume this initial compression as 'x'.

Force = 4 N/m × x

Using Newton's second law of motion, the equation becomes:

mass × acceleration = 4 N/m × x

Since both balls have the same mass and acceleration, we can rewrite the equation as:

2 kg × acceleration = 4 N/m × x

Simplifying the equation, we get:

acceleration = (4 N/m × x) / 2 kg

Given that the velocity of the balls after the spring is released is 10 m/s, we can use the equation of motion to relate the displacement and velocity:

velocity^2 = initial velocity^2 + 2 × acceleration × displacement

Since the initial velocity is zero, the equation becomes:

velocity^2 = 2 × acceleration × displacement

Plugging in the values, we have:

(10 m/s)^2 = 2 × acceleration × x

Simplifying the equation, we get:

acceleration = (10 m/s)^2 / (2 × x)

Equating the two expressions for acceleration, we have:

(4 N/m × x) / 2 kg = (10 m/s)^2 / (2 × x)

Simplifying the equation further, we get:

2 N/m × x^2 = 100 m^2/s^2

Solving for x, we find:

x^2 = 100 m^2/s^2 / 2 N/m

x^2 = 50 m

Taking the square root of both sides, we get:

x = √50 m

Hence, the displacement of the spring is equal to √50 m.

Substituting this value back into the equation for acceleration, we can find the acceleration produced in each ball:

acceleration = (4 N/m × √50 m) / 2 kg

Simplifying the equation, we find:

acceleration ≈ 4 ms^-2

Therefore, the acceleration produced in each ball is approximately 4 m/s².
