Answer #1

Given Spring length = 3.00 cm

Energy stored in spring U = 3.0 joules

3.0 = k * /2 ​​​​​​

= 2/3

Same spring to store a total of 12.0 joules of energy(​​​​​​)  

i.e

Energy stored in spring

12.0 = 2 * /6

= 36 cm

= 6 cm

​​​​​Compressing a spring( = 2/3)  6.00 cm from equilibrium stores joules of 12.0 joules of energy.

1. Steve, with mass m, is ready to squat jump Kale’s insecurities—represented by n moles of a solid with total mass M—out of Earth’s atmosphere. He decides to model his squat as a spring with constant k compressing vertically down a distance d from equilibrium, and the jump as releasing that spring, launching himself and Kale’s insecurities to a maximum height h above equilibrium. He does everything perfectly. a) When he gets to that maximum height, he finds that Kale’s...

A child’s toy consists of a m = 36 g monkey suspended from a spring of negligible mass and spring constant k. When the toy monkey is first hung on the spring and the system reaches equilibrium, the spring has stretched a distance of x = 17.7 cm, as shown in the diagram. This toy is so adorable you pull the monkey down an additional d = 4.6 cm from equilibrium and release it from rest, and smile with delight...
