Even though in this section you will be focused on a relationship between force and mass, it will be useful to figure out how fast the mass is moving as the table rotates, called the tangential speed. There are a few other piece you will need to find before you are ready to find the tangential speed of the mass. First, measure the radius of the mass's path' You can use any of the mass options for this I need a hint cm / co submissions used Score: 0/1 TANGENTIAL SPEED RADIUS MAss V D 20g ange @E 4.

When we have a graph that shows a relationship besides linear, it is helpful to linearize it. This means we do some kind of calculation with the quantity on the horizontal axis of the original graph. Then, we make a new graph with the calculated quantity on the horizontal axis to try and make a graph with a linear shape. The calculation it takes to make a straight line will depend on the relationship the original graph shows: Shape of Orlginal Graph New Horizontal Axis Linear x Parabola x2 Square root v'x Inverse 1/x Inverse square 11xZ Select the quantity you should plot on your horizontal axis to produce a linear TANGENTIAL SPEED RADIUS MASS graph v 0 mg @ Hint: Rep/ace "X" with the quantity that you plotted on your original horizontal axis f' 'I O I{ II >l I LBJ ' e) , m 2 16. If needed, use a column formula to linearize your graph. Use a curve fit to find the slope of your graph. 0.4 0.6 Record the value of the slope of your graph in Newtons per kilogram. 8 0 Make sure you get a correct answer before you move on to the next section!
