A spring 150-cm long extends to a length of 155 cm when it supports a load of 55 N. Determine the spring constant.

F = kx

x

x

F = 55 N

k = ?

Now, "x" in F = kx is x

Sorry, I know this is simple, I just am having a momentary lapse.

F = kx

x

_{1}= 1.5 mx

_{2}= 1.55 mF = 55 N

k = ?

Now, "x" in F = kx is x

_{2}-x_{1}, right? So the formula would be 55 = .05k?Sorry, I know this is simple, I just am having a momentary lapse.
