You are attempting to determine the spring constant of a rubber band. To do this you hang an 82 N weight from the rubber band and measure its length to be 0.62 m. You then hang a 195 N weight from it and measure the length to be 0.87 m. Now you can calculate the spring constant of the rubber band. What is it?

A student uses a rectangular carrot cantilever beam to find the spring constant, k, to determine its Youngs modulus. 10g increments are added to the apparatus and the displacement is measured each time. a. Using the data provided, plot a graph of F (applied force in N) on the y axis versus x (displacement of cantilever in mm) on the x axis. Include: - Horizontal error bars - Line of best fit – Two lines of worst fit b. Find...

5. In bungee jumping, it is obviously important to know in advance how far an elastic cord of un-stretched length L will stretch with a given weight attached to its end. In one model for this elongation, the cord is simply considered to be a weak spring with constant k and the person tied to the end of the cord is a point mass m. Air resistance and any pendulum motion of the cord mass system are ignored. Suppose a...

Graphical analysis is commonly used to determine unknown physical properties. For quantities that are linearly proportional to each other, physicists often use the slope of the best‑fit line to a scatter plot in order to determine the proportionality constant. A common physics lab experiment involves hanging different masses ?? from a spring of unknown spring constant ?. The resulting spring stretches Δ?? are then plotted versus the weight ??? of each hanging mass, where ? is the gravitational acceleration. What...

from the graph in Figure 2. 2 kg 100 N/m Foooo A student is conducting an experiment to analyze the mechanical energy of a block-spring system. The student places a block of mass 2kg on a horizontal surface and attaches the block to a horizontal spring of negligible mass and spring constant 100N/m, as shown in the figure. There is negligible friction between the block and the horizontal surface. The other end of the spring is attached to a wall....
