A certain spring has a spring constant k1 = 720 N/m as the spring is stretched from x = 0 to x1 = 39 cm. The spring constant then changes to k2 = 210 N/m as the spring is stretched to x2 = 67 cm. From x2 = 67 cm to x3 = 91 cm the spring force is constant at F3 = 115 N. Use the area under the curve to calculate the work, in joules, necessary to stretch the spring from x = 0 to x1.

Amoving company collects data about couches they move and displays the data in a table. the force along the ramp, the angle of the ramp, and the height the couch is raised to are shown. which statements correctly compare the work done to move the couches? check all that apply. the same amount of work is done for couches 1 and 3. the same amount of work is done for couches 2 and 3. the work for couch 1 is greater than the work for couch 2. the work for couch 2 is less than the work for couch 3. the work for couch 3 is greater than the work for couch 1. the work for couch 2 is greater than the work for couch 1.
