A mass of 2 kg is attached to a spring with constant 18 N/m. How far is the spring stretched?

A spring with a spring constant of 28.9 N/m is attached to different masses, and is stretched 5cm. What is the force exerted on the spring?

**drwls**, Wednesday, November 10, 2010 at 11:36amPart 1: A M=0.1 kg mass weighs F = Mg = 0.98 Newtons. The spring constant is

k = F/X . If you put X in meters (0.01 m), do the computation and you will get k in MKS units of N/m

Part 2:

Use the same Hooke's law formula,

k = F/X

Rearrange it to get X= F/k

The do the calculation. They told you what k is. You will have to convert the 2 kh mass to weight force.

Part 3: F = k X

In this case they tell you that X = 0.05 m

Do the numbers.
