Finding the Stiffness of the Rubber Band

To find the stiffness of the rubber band, we need to use Hooke's Law, which states that the force exerted by a spring or elastic material is directly proportional to the displacement or stretch of the material.

Hooke's Law can be expressed as:

F = k * x

Where: - F is the force applied to the rubber band - k is the stiffness or spring constant of the rubber band - x is the displacement or stretch of the rubber band

In this case, we know that the mass of the ball hanging from the rubber band is 100 grams, and the rubber band is stretched by 1 centimeter.

To find the stiffness of the rubber band, we need to determine the force applied to the rubber band. We can do this by considering the weight of the ball.

The weight of an object can be calculated using the formula:

Weight = mass * acceleration due to gravity

In this case, the acceleration due to gravity is approximately 9.8 m/s^2.

Therefore, the weight of the ball is:

Weight = 0.1 kg * 9.8 m/s^2 = 0.98 N

Now, we can use Hooke's Law to find the stiffness of the rubber band.

F = k * x

Substituting the values we have:

0.98 N = k * 0.01 m

Simplifying the equation, we can find the value of k:

k = 0.98 N / 0.01 m = 98 N/m

Therefore, the stiffness of the rubber band is 98 N/m.

Please note that the values used in this calculation are approximate and may vary depending on the specific properties of the rubber band and the accuracy of the measurements.
