1. Calculate the force required to stretch a spring with spring constant 0.20 N/m a distance of 5.0cm. (Note: 1N/m = 100N/cm)
2. A vertical spring stretches 5.0cm under a load of 100g. Calculate the spring constant.
3. A force of 600N compresses a spring with spring constant 30N/cm. Calculate the compression of the spring. (Note you can still use the equation F=kx, where x is the compression)
