How much work, in kj, can a spring whose spring constant is 6 kn/cm produce after it has been compressed 3 cm from its unloaded length?

  W= 27 KJ  

Explanation:

Given that

Spring constant ,K= 6 KN/cm

K= 6 x  10⁷ N/m

Displacement ,x= 3 cm = 0.03 m

The work done is given as

K=Spring constant

x=Displacement

Now by putting the values in the above equation

W=27000 J

The work done in KJ is given as

W= 27 KJ                   ( 1 K = 1000 )

Therefore the answer will be 27 KJ.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
