Question

1. A spring has an un stretched length of 10 cm. A 100g mass is added, and the spring stretches to a total length of 20cm, where the mass rests at equilibrium. What is the spring constant? m=100 g or 0.1kg x = 10cm or 0.1m f = kx k = f/x = mg/x k = 0.1 * 9.81 / 0.1 k = 9.81 N/m 2. Now, the same mass as in problem 1 is pulled down an additional 5cm, so that the length of the spring is 25cm, and then released. Draw a graph that shows the subsequent motion of the spring (as a function of time). On your graph, show the meaning of the amplitude and the period-include numbers!

m=100 g or 0.1kg
x = 10cm or 0.1m
f = kx
k = f/x = mg/x
k = 0.1 * 9.81 / 0.1
k = 9.81 N/m
