Question

a mass of 100 g is attached to a vertical spring with a spring constant k= 20n/m lower slowly until the spring start stretching. how much does the spring stretch?

Answer 1

The amount a spring stretches can be calculated using Hooke's Law, which states that the displacement of the spring is directly proportional to the force applied to it. In this case, the force applied to the spring is the weight of the mass attached to it.

Step-by-step explanation:

The amount a spring stretches can be calculated using Hooke's Law, which states that the displacement of the spring is directly proportional to the force applied to it. In this case, the force applied to the spring is the weight of the mass attached to it. The formula for Hooke's Law is:

F = k * x

where F is the force applied to the spring, k is the spring constant, and x is the displacement of the spring. Rearranging the formula, we have:

x = F / k

Given that the mass is 100 g, its weight can be calculated as:

weight = mass * g

where g is the acceleration due to gravity. Substituting the values into the equation, we can find the displacement of the spring.
