Hooke's law describes a certain light spring of unstretched length 35.0 cm. When one end is attached to the top of a door frame, and a 7.00-kg object is hung from the other end, the length of the spring is 47.00 cm. (a) Find its spring constant. kN/m (b) The load and the spring are taken down. Two people pull in opposite directions on the ends of the spring, each with a force of 150 N. Find the length of the spring in this situation. m

Step 1
First, we need to find the spring constant k. We know that Hooke's law is given by F = kx, where F is the force applied, x is the displacement from the equilibrium position, and k is the spring constant. Show more…

Hooke's law describes a certain light spring of unstressed length $35.0 \mathrm{cm} .$ When one end is attached to the top of a door frame and a $7.50-\mathrm{kg}$ object is hung from the other end, the length of the spring is $41.5 \mathrm{cm} .$ (a) Find its spring constant. (b) The load and the spring are taken down. Two people pull in opposite directions on the ends of the spring, each with a force of 190 $\mathrm{N}$ . Find the length of the spring in this situation.
