Work of 8 Joules is done in stretching a spring from its natural length to 2 m beyond its natural length What is the force (in Newtons) that holds the spring stretched at the same distance (2 m beyond its natural length)? Do this problem by hand and show all your steps.
a. Work of 2 Joules is done in stretching a spring from its natural length to 15 cm beyond its natural length. What is the spring constant k > 0? Don't forget to enter the correct units b. If the spring is stretched to the same distance (15 cm), what is the restoring force that pulls the spring back toward its equilibrium position? Restoring force- Don't forget to enter the correct units.
The work required to stretch a spring 1.2 meters beyond its natural length is 36 Joules. The force required to hold the spring at a length of 6 meters is 100 Newtons. Find the natural length of the spring.

(1 point) Finding the work done in stretching or compressing a spring. Hooke's Law for Springs. According to Hooke's law, the force required to compress or stretch a spring from an equilibrium position is given by F(x) = kx, for some constant k. The value of k (measured in force units per unit length) depends on the physical characteristics of the spring. The constant k is called the spring constant and is always positive. Part 1. Suppose that it takes...
