Find the extension of the spring

Answer 1

To find the extension of the spring, we can use Hooke's Law equation:

F = k * x

where:
F = force applied (in Newtons)
k = spring constant
x = extension of the spring (change in length)

Given that the original length is 20cm and the new length is 25cm, the extension of the spring would be:

Extension (x) = New Length - Original Length
Extension (x) = 25cm - 20cm
Extension (x) = 5cm = 0.05m

Now, we can rearrange Hooke's Law equation to solve for the spring constant k:

k = F / x
k = 50N / 0.05m
k = 1000 N/m

Therefore, the extension of the spring is 0.05m and the spring constant is 1000 N/m.
