Answer 2

Calculating the Force Required to Stretch a Spring

To calculate the force required to stretch a spring, you can use Hooke's Law, which states that the force required to stretch or compress a spring is directly proportional to the displacement of the spring from its equilibrium position.

Hooke's Law states that the force required to stretch or compress a spring is given by the formula:

F = kx

Where: - F = force applied to the spring (in newtons, N) - k = spring constant (in newtons per meter, N/m) - x = displacement of the spring from its equilibrium position (in meters, m)

Calculation

Given: - Spring constant, k = 125 N/m - Displacement, x = 0.03 m (3 cm converted to meters)

Using Hooke's Law, we can calculate the force required to stretch the spring:

F = kx F = 125 N/m * 0.03 m F = 3.75 N

Therefore, the force required to stretch the spring by 3 cm is 3.75 N.
