Question

Can someone please tell me what the spring constant is for the second spring? I thought I was correct... but I guess not.

Spring Mass (g) weight (N) Stretched Length (cm) (am1 3 Using plotting software. make a plot of Force Ma88 x versus AL. Be sure to convert your units sa necessary rams must be convertedto kilograms before mutiplying by 9, and rs must be comwerted to metere). Fit astreight line to the data, and determine the alope. This slope is the spring Spring Constant (N/n) Spring 1 702 Spring 2

Explanation / Answer

take

y2 = 0.491 N, x2 = 9.7 cm

y1 = 0.294 N, x1 = 6.6 cm

here we are taking force on y axis and extension on x axis.

so, spring constant, k = slope of the staright line

= (y2 - y1)/(x2 - x1)

= (0.491 - 0.294)/(9.7 - 6.6)

= 0.0635 N/cm

= 0.0635*100 N/m

= 6.35 N/m
