Answer 2

To calculate the change in length (delta * L), we can use Hooke's law, which states that the force required to extend or compress a spring is directly proportional to the displacement (change in length) and can be expressed as:

F = k * delta L

where: F = Force applied to the spring k = Spring constant (stiffness) in N/m (newtons per meter) delta L = Change in length of the spring (what we want to find)

Given: M = 10000 kg (mass of the object) k = 2000000 N/m (spring constant)

Now, we need to find the force applied to the spring. The force applied to the spring is the weight of the object attached to it, which can be calculated as:

F = M * g

where: M = Mass of the object (10000 kg) g = Acceleration due to gravity (approximately 9.81 m/s²)

Let's calculate the force first:

F = 10000 kg * 9.81 m/s² ≈ 98100 N

Now, we can find the change in length (delta * L) using Hooke's law:

F = k * delta L

Rearrange the formula to solve for delta * L:

delta L = F / k

Substitute the values:

delta L = 98100 N / 2000000 N/m delta L = 0.04905 m

So, the change in length (delta * L) of the spring is approximately 0.04905 meters.
